Abstract: A lensed antenna is provided. The lensed antenna includes a linear array of radiating units that are spaced apart from one another in a longitudinal direction. Each radiating unit includes a first radiating element and a second radiating element that is arranged proximate to the first radiating element. Either of the first radiating element or the second radiating element is operable to resonate at a first frequency and a combination of the first radiating element and the second radiating element is operable to resonate at a second frequency that is different from the first frequency. A lens is positioned to receive electromagnetic radiation from at least one of the radiating units.

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: A cellular base station antenna having improves squint performance is provided. The antenna includes a ground plane, a first plurality of radiating elements supported over the ground plane by microstrip support PCBs, and a second plurality of radiating elements supported over the ground plane by stripline support PCBs. The first and second pluralities of radiating elements are arranged in at least one array of low band radiating elements, and the quantities of first and second pluralities of radiating elements are selected to reduce squint of a beam produced by the at least one array. The first plurality of radiating elements may be located below the second plurality of radiating elements in the array. The array may be arranged in a linear column or a staggered column. In one example, the first plurality of radiating elements comprises four radiating elements and the second plurality radiating elements comprises two radiating elements.
Abstract translation: 提供了一种提高了斜视性能的蜂窝基站天线。 天线包括接地平面，通过微带支撑PCB支撑在接地平面上的第一多个辐射元件，以及通过带状线支撑PCB支撑在接地平面上的第二多个辐射元件。 第一和第二多个辐射元件被布置在低频辐射元件的至少一个阵列中，并且选择第一和第二多个辐射元件的量以减少由至少一个阵列产生的光束的斜视。 第一组多个辐射元件可以位于阵列中的第二组多个辐射元件的下方。 阵列可以布置在线性列或交错列中。 在一个示例中，第一多个辐射元件包括四个辐射元件，并且第二多个辐射元件包括两个辐射元件。

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。
