        • A panel antenna having a variable phase shifter module with at least one main-PCB having an input trace coupled to a wiper junction. An arcuate trace on the main-PCB extending between a first output trace and a second output trace, the arcuate trace having an arc center proximate the wiper junction. A wiper-PCB having a linking trace thereon; the wiper-PCB rotatably coupled to the main-PCB proximate the wiper junction with the linking trace facing the first main-PCB. Because the linking trace faces the main-PCB, the wiper-PCB may be formed from inexpensive and structurally resilient substrate material. The linking trace coupling the wiper junction with the arcuate trace. Multiple arcuate traces may be linked to further output traces to add additional outputs, each having variable phase shift between them, depending upon the position of the wiper-PCB. Multiple main-PCBs may be stacked upon each other and the wiper-PCBs of each controlled by a common linkage.
        • 一种具有可变移相器模块的面板天线,具有至少一个主PCB,其具有耦合到擦拭器结的输入迹线。 主PCB上的弓形迹线在第一输出迹线和第二输出迹线之间延伸,弓形迹线具有靠近擦拭器结的圆弧中心。 其上具有连接痕迹的刮水器PCB; 擦拭器PCB可靠地连接到主PCB,靠近擦拭器连接处,连接迹线面向第一主PCB。 由于连接迹线面向主PCB,擦拭器PCB可以由廉价且结构有弹性的基底材料形成。 连接迹线将雨刷结与弧形迹线相连。 多个弧形迹线可以链接到另外的输出迹线以添加附加的输出,每个输出根据刮水器PCB的位置而具有可变的相移。 多个主PCB可以彼此堆叠,并且每个主要PCB通过公共连接来控制。

        • 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。
