    • 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.
    • 可变差分移相器包括隔离元件,提供输出端口之间的良好隔离,良好的回波损耗和减少的反射。 在一个实施例中,威尔金森分路器被并入刮水器类型的可变差分移相器的雨刷臂中。 在另一个实施例中,线性移相器包括Wilkinson分压器。 还公开了多级实施例。 可变差分移相器可以与混合耦合器组合使用以提供隔离的可变功率分配器。 可变差分移相器可以用于各种馈电网络和天线阵列以改变波束倾斜,波束方位角和波束宽度。 结合了移相器的天线具有低功率波束宽度与频率和减小的旁瓣的低变化。

    • The present invention provides a capacitively coupled stripline to microstrip transition which comprises a stripline, a microstrip, an upper conductive ground plane, a lower conductive ground plane, an insulating layer and an insulating fixing component. The stripline is positioned between the upper conductive ground plane and the lower conductive ground plane, and has a stripline overlap section. The microstrip is mounted on the upper conductive ground plane, and has a microstrip overlap section which penetrates the upper conductive ground plane. Wherein the microstrip overlap section, the insulating layer and the stripline overlap section are attached uniformly and tightly in sequence and fixed together by the insulating fixing component. The present invention further provides an antenna comprising this transition.

    • An antenna comprising a plurality of sub-arrays and methods and structure for restoring performance after a transceiver failure is provided. Each sub-array may include a power divider/combiner network, a first radiating element coupled to a first port of the power divider/combiner network, a second radiating element coupled to a second port of the power divider/combiner network, and a transceiver coupled to a third port of the power divider/combiner network. An adjustable power supply may be coupled to each transceiver, the adjustable power supply having current monitors to detect at least one failure state of a transceiver, and a power compensation mode to increase absolute power to a transceiver in a non-failed state. The adjustable power supply provides a first voltage in normal operation and a second voltage, where the second voltage is higher than the first voltage in power compensation mode.
