The present invention relates to a sealing member for a base station antenna and a base station antenna comprising the same as well as a method and device for manufacturing the sealing member. The sealing member (2) is flexible and resilient and is configured to form a seal between an open end (5) of a radome (3) and an end cap (1) of the base station antenna. The sealing member is an elongated sealing strip having two ends, wherein the two ends of the sealing member are lappable with each other, and the sealing member has a groove extending over its entire length, which groove is defined by two side limbs and a bottom limb connecting the two side limbs of the sealing member, wherein the groove is configured to engage with an edge of the open end (5) of the radome, and wherein the sealing member is configured to be received in an annular recess of the end cap (1) and isolate an interior of the radome (3) from the environment. The sealing member can be manufactured cheaply and can be flexibly applied to base station antennas with different sizes.

A method of operating a User Equipment (UE) device may be provided. Installation data relating to an antenna of a radio access network (RAN) node may be obtained, wherein the installation data includes physical installation data including at least one of a height of the antenna, a direction of the antenna, and/or a tilt of the antenna. The installation data may be transmitted from the UE device to a management system for a wireless communication network including the RAN node. Related radio nodes and management nodes are also discussed.

A 4G and/or 5G signal communication unit is able to be attached to a glazing unit that includes housing with at least side parts and a cover. A communication device is fixed inside the housing and is surrounded by the side parts and the cover. The 4G and/or 5G signal communication device has at least one antenna. The housing includes a matching element. A communication system includes a glazing unit, at least the 4G and/or 5G signal communication unit and a provider fixed station or active or passive repeater, which is placed at least at 1 m outside from the glazing unit. The 4G and/or 5G signal communication unit is fixed to the glazing unit at the opposite side from the provider fixed station or active or passive repeater.

Embodiments of the disclosure include a Radio Detection and Ranging (Radar) system with reduced transmitter antenna and receiver antenna mutual coupling. The radar system includes a transmitter antenna disposed on a first side of the dielectric substrate and a receiver antenna disposed on the same side of the dielectric substrate. The radiation boundaries of the transmitter antenna and the receiver antenna are substantially parallel to a line connecting centroids of the transmitter antenna and the receiver antenna. The radar system also includes a ground plane disposed on a second side of the dielectric substrate, opposite to the first side, operatively connected to the transmitter antenna and the receiver antenna through probes. The ground plane comprises at least one groove, separating vertical projections of the transmitter antenna and the receiver antenna on the ground plane.

A low-PIM dual pipe clamp and associated mounting bracket for securing a first pipe transverse to a second pipe at a cellular base station antenna site. The dual pipe clamp accommodates a range of pipe diameters with lower PIM generation, cost, and weight characteristics compared to conventional dual pipe clamps traditionally used at cell sites. The low-PIM dual pipe clamp minimizes the number of parts to upper and lower mounting brackets connected by linear threaded rod connectors, such as bolts, avoiding the use of U-bolts known to create PIM interference in conventional designs. The dual pipe clamp secures first and second pipes against each other in transverse orientations (e.g., horizontal and vertical), as typically utilized to mount antennas at cellular base stations. Each mounting bracket includes first and second pipe restrainers that bias the first and second pipes against each other as the threaded rod connectors are tightened.

This application proposes multi-beam antenna systems using spherical lens are proposed, with high isolation between antenna ports and compatible to 2×2, 4×4, 8×8 MIMO transceivers. Several compact multi-band multi-beam solutions (with wideband operation, 40%+, in each band) are achieved by creating dual-band radiators movable on the track around spherical lens and by placing of lower band radiators between spherical lenses. By using of secondary lens for high band radiators, coupling between low band and high band radiators is reduced. Beam tilt range and side lobe suppression are improved by special selection of phase shift and rotational angle of radiators. Resultantly, a wide beam tilt range (0-40 degree) is realized in proposed multi-beam antenna systems. Each beam can be individually tilted. Based on proposed single- and multi-lens antenna solutions, cell coverage improvements and stadium tribune coverage optimization are also achieved, together with interference reduction.
