Furthermore, once the antenna is positioned in a desired angular orientation, tightening of the fasteners connecting the mounting bracket with the intermediate member is performed to secure the antenna at a particular orientation.

[0050] Reference will now be made to the exemplary embodiments of the disclosure, as illustrated in the accompanying drawings. Wherever possible same numerals will be used to refer to the same or like parts.

[0051] Embodiments of the disclosure are described in the following paragraphs with reference to FIGS. 1 to 7. In FIGS. 1 to 7, the same element or elements which have same functions are indicated by the same reference signs.

[0052] FIG. 1 is a perspective view of an arrangement in which an exemplary mounting assembly 100 has been utilized to mount a base station antenna 200 to a support structure 300. The support structure 300 may be defined as a pole or any similar vertical structure rigidly fixed to a surface. The mounting assembly 100 is connected near a bottom end cap 200b of the antenna 200. A centre gravity of the antenna 200 may be considered while determining the position of mounting the mounting assembly 100 to the base station antenna 200. In other words, the position of fixing the mounting assembly 100 with the antenna 200 may be determined based on the centre of gravity of the antenna 200. The position for fixing the mounting assembly 100 may be selected to maintain the centre of gravity of the antenna 200 near the position of the mounting assembly 100 (and in some embodiments the centre of gravity is slightly above the mounting assembly 100). The position of the mounting assembly 100 may prevent bending of the antenna 200.

[0053] In an exemplary embodiment of the present disclosure, the mounting assembly 100 is employed with antennas 200 having an antenna length less than 1000 mm. Further, the mounting assembly 100 may be configured to secure the antenna 200 weighing up to 15 kg. The mounting assembly 100 may be connected at a position between 200 mm to 300 mm length of the antenna 200 measured from the bottom end cap 200b of the antenna 200 having antenna length of 1000 mm. However, the mounting assembly 100 provided in the present disclosure, is not limited to use with the antenna 200 as specifically described herein.

[0054] Referring to FIGS. 1-3, the mounting assembly 100 comprises a pair of clamp brackets 102, a mounting bracket 104 and a lead screw sub-assembly 106. The pair of clamp brackets 102 is configured to be connected to the support structure 300. The mounting bracket 104 is configured to be connected to the antenna 200 at the pre-determined position of the antenna 200. The lead screw sub-assembly 106 is configured to facilitate a tilt angle adjustment to the antenna 200 when required.

[0055] Referring to FIGS. 3 and 4, each of the clamp bracket of the pair of clamp brackets 102 comprise a first plate 102a and two side plates 102b and 102c extending perpendicularly from opposite edges of the first plate 102a, as shown in FIG. 4, such that a cross-section of the clamp bracket, as seen in a side view, forms a C-shaped profile. Each clamp bracket 102 includes a plurality of serrations 102d formed at a centre portion of each of the side plates 102b and 102c. The plurality of serrations 102d are configured to provide grip to the pair of clamp brackets 102 for mounting the clamp brackets on the support structure 300. As shown in FIG. 4, the plurality of serrations 102d formed on a curved portion of the side plates 102b, 102c in order to provide firm grip to the clamp brackets 102, while mounting to the cylindrical shaped support structure 300. The side plates 102b, 102c may have different shaped profiles depending upon an outer profile of the support structure 300, for instance—if the support structure has a polygonal shaped cross-section, then the side plates of the clamp brackets are formed with polygonal shaped portions at the centre of the side plates. The first plate 102a of each of the clamp brackets 102 is provided with a plurality of holes to receive long bolts 102e to connect clamp brackets 102 with the support structure 300. Each of the long bolts 102e is locked by a corresponding nut 102f to secure the clamp brackets 102 with the support structure 300. Although the exemplary configuration of the mounting assembly, as disclosed and shown in the present disclosure, describes long bolts and nuts for mounting the clamp brackets on the support structure, any other suitable fastening means may also be utilized to mount the clamp brackets 102 on the support structure 300.

[0056] Referring to FIG. 4, one of the side plates 102b, 102c of at least one of the clamp bracket 102 is provided with a first flange 102g. The first flange 102g extends from at least one of the side plates 102b, 102c of at least one of the clamp bracket 102. In the exemplary embodiment shown in FIG. 4, the first flange 102g extends from the side plate 102b of the clamp bracket 102. The first flange 102g may also be provided on both the side plates 102b, 102c of the at least one clamp bracket 102. Although the exemplary configuration of the mounting assembly, as disclosed and shown in the present disclosure, describes the first flange 102g is defined having a L-shaped structure to provide strength to the first flange 102g, any other suitable structure of the first flange 102g may be utilized which provides sufficient strength to the lead screw sub-assembly 106. In an embodiment, the first flange 102g may be integrally formed with the clamp bracket 102. In alternate embodiments, the first flange 102g may be externally attached to the clamp bracket 102 by permanent fixing means, for example—welding, soldering etc.

[0057] In an embodiment of the present disclosure, the first flange 102g is provided on both clamp brackets 102 of the mounting assembly 100 to provide sufficient strength and provisions for mounting the lead screw sub-assembly 106 to the pair of clamp brackets 102. The first flange 102g provided on the pair of clamp brackets 102 is defined with a threaded hole 102h formed on a vertical plate of the first flange 102g.

[0058] Referring again to FIG. 2 and FIG. 3, the mounting assembly 100 comprises an intermediate member 108 configured to be connected to a first clamp bracket of the pair of clamp brackets 102 arranged proximal to the mounting bracket 104. The intermediate member 108 is connected to the first clamp bracket by means of the long bolts 102e adapted to pass through the intermediate member 108 and each of the pair of clamp brackets 102. The intermediate member 108 may be integrally formed with the first clamp bracket of the pair of clamp brackets 102. Although the exemplary configuration of the mounting assembly 100, as disclosed and shown in the present disclosure, describes the intermediate member 108 defined as a U-shaped clamp, any other suitable structure may be utilized of the intermediate member 108 to pivotably connect the intermediate member 108 with the mounting bracket 104. The intermediate member 108 comprises a third pair of flanges 108a formed at opposite ends thereof. The intermediate member 108 is coupled to the mounting bracket 104 for supporting the mounting bracket 104 and also to facilitate the pivotal movement to the mounting bracket 104, during adjustment in tilt angle of the antenna 200. The intermediate member 108 is defined with provisions to pivotably couple the mounting bracket 104 by fasteners 108b and locking nuts 108c. The locking nuts 108c are configured to secure the mounting bracket 104 to the intermediate member 108 when the tilt angle adjustment of the antenna 200 is not required. The intermediate member 108 may be formed with a rib-like structure 108d at bending portion of the third pair of flanges 108a to enhance strength of the intermediate member 108.

[0059] The mounting bracket 104 comprises a second pair of flanges 104a formed at opposite ends of the mounting bracket 104. Each flange of the third pair of flanges 108a is connected with a corresponding flange of the second pair of flanges 104a for coupling the intermediate member 108 with the mounting bracket 104 by the fasteners 108b and locking nuts 108c. The third pair of flanges 108a is pivotably coupled with the second pair of flanges 104a, such that the second pair of flanges 104a is configured to pivot around the fasteners 108b. According to an embodiment of the present disclosure, the mounting bracket 104 comprises an elongated slot 104b defined in a side wall 104c of the mounting bracket 104. The side wall 104c of the mounting bracket 104 is defined inclusive of one of the flange of second pair of flanges 104a. The elongated slot 104b is positioned on the side wall 104c of the mounting bracket 104 such that that the elongated slot is eccentric to a mounting axis of the fasteners 108b.

[0060] Referring to FIGS. 2-6, the lead screw sub-assembly 106 comprises a lead screw 106a engaged with at least one clamp of the pair of clamp brackets 102 and an adjustment bracket 106d coupled at a first end 106f of the lead screw 106a and configured to allow a pivotal movement of the mounting bracket 104 with respect to the pair of clamp brackets 102. The first end 106f of the lead screw 106a is defined as an end proximal to the mounting bracket 104. The lead screw 106a is rotatable within the at least one clamp bracket 102 for adjusting a tilt angle of the antenna 200. The lead screw 106a comprises a second end 106s opposite to the first end 106f of the lead screw 106a. The second end 106s of the lead screw 106a comprises a head 106h of the lead screw 106a. The head 106h is provided to facilitate grip to hold and rotate the lead screw 106a during adjusting the tilt angle of the antenna 200. Alternatively, the rotation of the lead screw 106a may be governed by using an actuator coupled to the head 106h of the lead screw. The actuator may either be controlled remotely by an operator or by a switch mounted to the support structure 300.

[0061] The lead screw 106a further comprises a first portion 106b adapted to rotate within the at least one clamp bracket 102 and a second portion 106c adapted to receive a locking nut (not shown in the figures) for coupling the adjustment bracket 106d with the lead screw 106a at the first end 106f of the lead screw 106a. A diameter of the second portion 106c of the lead screw 106a is less than a diameter of the first portion 106b of the lead screw 106a. The variation in diameter of the first portion and second portion of the lead screw 106a provides a step profile structure to the lead screw 106a at the first end 106f. The step-profile of the lead screw 106a limits the movement of the adjustment bracket 106d towards the second end 106s of the lead screw by abutting the adjustment bracket 106d against the second portion 106c of the lead screw 106a.

[0062] Once again referring to FIGS. 2-4, the lead screw 106a is configured to engage with the threaded holes 102h provided on each of the first flange 102g of the pair of clamp brackets 102. The first portion 106b of the lead screw 106a is defined with a plurality of external threads adapted to rotatably engage with threads formed on holes 102h of each of the first flange 102g. The threaded engagement of the lead screw 106a with each flange 102g of the pair of clamp brackets 102 facilitates the transformation of rotational movement of the lead screw 106a to a linear movement of the lead screw 106a. The linear movement of the lead screw 106a exerts a push/pull force onto the mounting bracket 104, during the tilt angle adjustment of the antenna 200.

[0063] Referring to FIG. 7, the adjustment bracket 106d comprises a base plate 106e and a pair of arms 106i extending perpendicularly from the opposite edges of the base plate 106e. The base plate 106e is defined with a first aperture 106g adapted to receive the second portion 106c of the lead screw 106a. The adjustment bracket 106d is provided with a second aperture 106j formed on each of the pair of arms 106i to receive the connecting pin 106k. Once the adjustment bracket 106d is secured at the first end 106f of the lead screw 106a, one of the second pair of flanges 104a having the elongated slot 104b is positioned between the pair of arms 106i of the adjustment bracket 106d. As shown in FIG. 3, the connecting pin 106k is allowed to pass through the second apertures 106j and the elongated slot 104b to movably connect the adjustment bracket 106d with the mounting bracket 104. The connecting pin 106k is locked into a fixed position by inserting a cross-wire or cotter pin 106m into a hole provided in the connecting pin 106k. to the mounting bracket. The elongated slot 104b on the mounting bracket 104 is configured to receive and guide the connecting pin 106k of the adjustment bracket 106d. The clockwise rotation of the lead screw 106a initiates a linear movement of the lead screw 106a towards the mounting bracket 104 exerting a push force on the mounting bracket 104 by the connecting pin 106k. The counter-clockwise rotation of the lead screw 106a initiates linear movement of the lead screw 106a away from the mounting bracket 104 exerting a pull force on the mounting bracket 104 by the connecting pin 106k. The rotation of the lead screw 106a moves the connecting pin 106k within the elongated slot 104d of the mounting bracket 104 for adjusting the tilt angle of the antenna 200.

[0064] In another embodiment of the present disclosure a method for adjusting a tilt angle of an antenna 200 is disclosed. The antenna 200 is connected to a mounting bracket 104 of a mounting assembly 100. The method comprises the step of: loosening of fasteners 108b adapted to connect the mounting bracket 104 with an intermediate member 108. The method further comprises the step of: applying rotational movement to a lead screw 106a connecting the mounting bracket 104 with one of a pair of clamp brackets 102, such that an adjustment bracket 106d secured to the lead screw 106a exerts a push force or pull force onto the mounting bracket 104 to facilitate pivotal movement of the mounting bracket 104 around the fasteners 108b for adjusting a tilt angle of the antenna 200 with respect to the pair of clamp brackets 102. The method further comprises: tightening the fasteners 108b connecting the mounting bracket 104 with the intermediate member 108 to secure the antenna 200 at a particular orientation.

[0065] The clockwise rotation of the lead screw 106a facilitates pivotal movement of the antenna 200 in a down-tilt direction. The down-tilt direction is defined as a direction of movement of the antenna 200 when the bottom end cap portion of the antenna 200b moves towards the support structure 300. The mounting assembly 100 provides at least 0-15° down tilt movement of the antenna 200, but is not limited to the same. The counter clockwise rotation of the lead screw 106a facilitates pivotal movement of the antenna 200 in an up-tilt direction. The up-tilt direction is defined as a direction of movement of the antenna 200 when the bottom end cap portion of the antenna 200b moves away from the support structure 300. The mounting assembly 100 provides at least 0-5° up-tilt movement of the antenna 200, but not limited to the same.

[0066] The antenna 200 may comprise a bumper element fixed at the bottom end cap 200b of the antenna 200 to prevent damage caused to the antenna 200 during excess angular movement of antenna 200. The bumper element may be formed from an elastic material which intends to absorb shock on the antenna 200 during performing the tilt angle adjustment of the antenna 200.
