    摘要： A flat-panel repeater includes a housing having a pair of oppositely facing surfaces, at least one antenna element mounted to each of the surfaces for radiating energy in a direction opposite to that of an antenna element mounted to the other of the surfaces, and an electronic circuit mounted within the housing and operatively coupling signals between at least one antenna element on each of the oppositely facing surfaces of the module. Isolation between the antennas on opposite sides of the repeater is improved by various techniques, such as use of adaptive cancellation which removes a significant portion of the feedback signal power, therefore increasing the total system isolation by the same amount. This additional isolation can be used to achieve greater system gain, and therefore significantly extend the range of the system. The repeater may also include a beamforming arrangement for creating a desired antenna pattern of one antenna relative to a base station and a desired antenna pattern of the other antenna relative to subscriber equipment.

    摘要： An antenna system includes a plurality of cascading power dividers that work in conjunction with a plurality of mechanical phase shifters to vary a beamwidth and/or an azimuth scan angle of a beam that radiates from active columns. Each phase shifter has an independent remotely controlled drive and is directly electrically connected to a respective radiating column. The radiating columns include cross dipole antenna elements.

    摘要： Systems and methods of testing active digital radio antennas are presented. Systems and methods can test the active digital radio antenna functioning as both a radio and as an antenna and can test both the transmit and receive performance of the antenna. An electromagnetic probe can scan the antenna to perform the testing and couple to the elements of the antenna using radio frequency signals propagated in the air, as opposed to direct cabling.

    摘要： A variable differential phase shifter including an isolation element providing good isolation between output ports, good return loss and reduced reflections. In one embodiment a Wilkinson divider is incorporated in the wiper arm of a wiper type variable differential phase shifter. In another embodiment a linear phase shifter incorporates a Wilkinson divider. Multistage embodiments are also disclosed. The variable differential phase shifter may be used in combination with a hybrid coupler to provide an isolated variable power divider. The variable differential phase shifter may be utilized in a variety of feed networks and antenna arrays to vary beam tilt, beam azimuth and beam width. Antennas incorporating the phase shifter exhibit low variation of half power beam width with frequency and reduced side lobes.
