    • A low sidelobe beam forming method and dual-beam antenna schematic are disclosed, which may preferably be used for 3-sector and 6-sector cellular communication system. Complete antenna combines 2-, 3- or -4 columns dual-beam sub-arrays (modules) with improved beam-forming network (BFN). The modules may be used as part of an array, or as an independent 2-beam antenna. By integrating different types of modules to form a complete array, the present invention provides an improved dual-beam antenna with improved azimuth sidelobe suppression in a wide frequency band of operation, with improved coverage of a desired cellular sector and with less interference being created with other cells. Advantageously, a better cell efficiency is realized with up to 95% of the radiated power being directed in a desired cellular sector.

    • 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。
