  • Patent number: 11576253
    Abstract: Printed circuit boards for a base station antenna include a substrate layer, and a first conductive trace and a second conductive trace which are printed on the substrate layer and cross each other. The first conductive trace has two trace sections separated by the second conductive trace. Adjacent ends of the two trace sections separated by the second conductive trace are connected electrically by a jumper. The jumper has an electrical conductor, is isolated electrically from the second conductive trace and is fixed on the printed circuit board. The electrical conductor and the two trace sections are connected electrically at adjacent ends. The printed circuit board allows flexible wiring of the conductive traces on the printed circuit board.

  • Publication number: 20230018326
    Abstract: 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.
