Abstract: A tilt adapter configured to facilitate a desired tilt of a first radio frequency (RF) band and a second RF band of an antenna is disclosed. The antenna supports two or more frequency bands, in which the vertical tilt of each of the supported frequency bands is separately controlled by a coarse level of phase shifting, but commonly controlled by a fine level of phase shifting.

Abstract: A small cell cellular base station includes an eight port radio and an eight-port base station antenna that has four linear arrays of dual-polarized radiating elements. Each of the linear arrays has a different azimuth boresight pointing direction and each dual-polarized radiating element includes first and second radiators that have respective directional radiation patterns. The radio is configured to determine and apply a first set of amplitude and phase weights to RF signals that are received through the eight ports of the antenna, and to apply a second set of amplitude and phase weights to RF signals that are output by the radio to the eight ports of the antenna.

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.

Abstract: A higher band radiating element for use in a multiband antenna includes first and second dipole arms supported by a feedboard. The feedboard includes first and second matching circuits, each comprising a capacitor-inductor-capacitor (CLC) matching circuit. The matching circuit further includes a CM tuning circuit connecting a portion of the matching circuit to ground via a microstrip trace selected to pass lower band currents while blocking higher band currents. The CM tuning circuit moves the common mode resonance of the higher band support PCB down below the operating frequency of additional, lower band radiating elements present in the multiband antenna, which is preferable to moving the common mode resonance above the lower band frequencies.
Abstract translation: 用于多频带天线的较高频带辐射元件包括由馈电板支撑的第一和第二偶极臂。 馈线板包括第一和第二匹配电路，每个包括电容 - 电感 - 电容（CLC）匹配电路。 该匹配电路还包括CM调谐电路，该CM调谐电路通过被选择为传递较低频带电流同时阻挡较高频带电流的微带线迹将匹配电路的一部分连接到地。 CM调谐电路将较高频带支持PCB的共模谐振下移到多频带天线中存在的附加低频辐射元件的工作频率以下，这优于将共模谐振移到低频带以上。

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.
