An antenna assembly may include an antenna element, a radome structure disposed proximate to the antenna element and including a plurality of plasma elements, a driver circuit operably coupled to the plasma elements to selectively ionize individual ones of the plasma elements, and a controller. The controller may be operably coupled to the driver circuit to provide control of plasma density of the individual ones of the plasma elements. The plasma elements may include respective enclosures. At least some of the enclosures may have at least two peripheral edge surfaces substantially fully contacted by corresponding peripheral edge surfaces of adjacent enclosures at at least one section along a longitudinal length thereof.

The present invention provides an arch structure for multi-band base station antenna, the arch structure comprises two interface units for connecting with the side edge of a reflector, and a plurality of snap-fits for fixing with the bottom of the reflector, wherein at least two snap-fits in the plurality of snap-fits are not arranged on a projection mid-axis of the arch structure. According to the arch structure of the present invention, it can effectively avoid the interference between the arch structure and the dipole or dipole isolation wall, and enhance the stability of arch structure, so that the width of the arch structure can be reduced and the manufacturing cost can be saved.

A transmitter comprises a main body case, a controller that is provided inside the main body case, a communication unit that is connected to the controller, and an elongated antenna unit that is connected to the communication unit. The antenna unit is disposed along an inner wall surface of the main body case.

A recessed antenna that includes a recessed plane formed in a conductive surface. An antenna is disposed on the recessed plane. A cavity is formed beneath the recessed plane. A circuit board is disposed in the cavity. The circuit board is electrically coupled to the antenna. A cover is disposed over the antenna, the cover protecting the antenna from abrasion.

The present disclosure relates to a base station antenna. The base station antenna comprises: a reflector and radome supports mounted on the reflector, wherein the reflector comprises a body portion and a bent portion, the bent portion including at least a first section that is connected to and bent relative to the body portion of the reflector, wherein one or more arrays of radiating elements are mounted on or above the body portion of the reflector, wherein the radome support includes a support portion for supporting the radome and a mating portion for mating with the reflector, wherein a first support limiting portion is provided on the mating portion of the radome support, a first reflector limiting portion mating with the first support limiting portion is provided on the body portion of the reflector, and the first support limiting portion mates with the first reflector limiting portion to limit at least the position of the radome support in a width direction H. This enables the radome supports to be mounted on the reflector at an efficient and reliable manner.

The present invention is a pole-mountable shroud assembly enclosing one or more wireless telecommunications transceivers and antennas, which extend from the pole and are rigidly attached to the pole by one or more transceiver brackets. A generally circular stationary panel is rigidly attached to the pole, and a generally annular, segmented jacked panel is attached to the pole at a vertical separation distance from the stationary panel. A panel jack, such as a screw or spring jack, connects the jacked panel to the pole so that the panel separation distance and the jacked panel circumference are adjustable. A very thin (not more than one-tenth the minimum transmission wavelength) fabric membrane shroud wraps around the circumference of the two panels, so as to form a generally cylindrical shroud enclosure which surrounds the transceivers/antennas. The panel jack is operative to tension, both vertically and radially, the fabric membrane shroud around the shroud enclosure.

A transmitter comprises a main body case, a controller that is provided inside the main body case, a communication unit that is connected to the controller, and an elongated antenna unit that is connected to the communication unit. The antenna unit is disposed along an inner wall surface of the main body case.

Invention relates to a radome casing and method for its manufacturing. The radome casing comprises walls (6, 11) of composite material which includes reinforcement fibers (8) and matrix resin (19) binding the fibers together. The walls include a radiation transmission window (11) through which the radiation of a radome antenna passes when the radome antenna (2) is mounted inside the radome casing (1). The amount of fibers in the radiation transmission window (11) is reduced to be less than 40-5% of the amount of fibers elsewhere in the casing walls (6). The reduction of reinforcement fibers in the radiation transmission window (11) reduces attenuation of the high frequency radiation.

A radome assembly of an aircraft includes a shell having an elongated shape wherein the shell defines a first opening having a diameter of a first dimension and is positioned within a first end portion of the shell. The shell defines a second opening having an elongated shape which extends along a length of the shell and has a second dimension which is greater than the first dimension. First fastener extends through the first opening and is engaged with a first surface associated with a first structural element and resists movement of the shell and the first structural element relative to one another. Second fastener extends through the second opening and is engaged with a second surface associated with the first structural element such that the shell is moveable along the length of the shell relative to the first structural element.

A radar measurement device with at least one transmitter to emit electromagnetic waves, the at least one transmitter being arranged inside a housing. The radar measurement device is intended to be securely and lastingly attachable to a flexible wall. For this purpose, at least a portion of the housing has an elastically deformable design. Furthermore, the arrangement of a radar measurement device to a fillable container is described.
