Actuator device for driving a phase shifter including a lead screw that can be automatically locked
The present invention relates to a transmission device for a phase shifter and an actuator device for a phase shifter. The transmission device includes a support, a lead screw nut mechanism and an automatic locking device. The automatic locking device includes a shaft connector rotatably supported on the support and configured to be in transmission connection with a driven connector of a driving device; a locking connector which is in transmission connection with the shaft connector, is in transmission connection with the lead screw, has a locking element and is movable relative to the shaft connector and the lead screw; and a locking spring. When the driven connector is decoupled to the shaft connector, the locking spring biases the locking connector in a first position, in which the locking element engages a counter-locking element on the support.

Low-PIM dual pipe clamp for cellular base station antenna sites
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.
Multi-beam MIMO antenna systems and methods
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.
