Abstract

Quad-polarization reconfigurable antenna consists of a three-layered polarizer, and an 8 × 8 source antenna is investigated in the Ka band. By changing the orientation of each layer, the antenna can radiate horizontally polarized, vertically polarized, left-hand and right-hand circularly polarized electromagnetic waves. The 8 × 8 horn array is employed as the source antenna, enhancing the antenna gain and expanding the operating bandwidth. The polarizer and the source antenna are fabricated by 3-D printing technology using photopolymer and aluminum alloy. Excellent operating performance, including impedance bandwidth of 51.1%, gain of up to 24.8 dBi, dual circular polarization overlap bandwidth of 41.3%, and quad-polarization overlap bandwidth of 24.6%, is obtained experimentally by the fabricated prototype. The proposed antenna with promising performance is valuable to emerging millimeter-wave applications.

基于三层极化器的宽带高增益四极化可重构天线

四极化可重构天线由三层极化器组成，在Ka波段研究了8 × 8源天线。通过改变每一层的方向，天线可以辐射水平极化、垂直极化、左圆极化和右圆极化电磁波。采用8 × 8喇叭阵列作为源天线，提高了天线增益，扩大了工作带宽。偏振片和源天线采用3d打印技术制备，材料为光聚合物和铝合金。实验结果表明，该系统具有良好的工作性能，阻抗带宽为51.1%，增益高达24.8 dBi，双圆极化重叠带宽为41.3%，四圆极化重叠带宽为24.6%。该天线具有良好的性能，对新兴的毫米波应用具有重要价值。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
