摘要
本文介绍了一种新型 E 平面和 H 平面波束宽度可重构多输入多输出 (MIMO) 天线。该天线由四个二维定向可重构天线元件组成，利用正内负（PIN）二极管在 E 平面和 H 平面实现稳定的波束宽度重构。对制造出的原型进行的模拟和测试结果表明，该天线的工作频率在 2.52 至 2.68 GHz 之间的四种不同状态。两个平面的波束宽度可在大约 65° 和 95° 之间切换。单元之间的隔离度超过 25 dB，辐射性能稳定，效率高。该天线特别适合 5G 室内通信应用。
E- and H-plane beamwidth-reconfigurable MIMO antenna
A novel E- and H-plane beamwidth-reconfigurable Multiple Input Multiple Output (MIMO) antenna is presented here. The antenna consists of four two-dimensional directional reconfigurable antenna elements that utilizes Positive-Intrinsic-Negative (PIN) diodes to achieve stable beamwidth reconfiguration in both the E-plane and the H-plane. Simulated and testing results of the fabricated prototype demonstrate that the operating frequency of the antenna ranges from 2.52 to 2.68 GHz across four different states. The beamwidth can switch between approximately 65° and 95° in both planes. The isolation between units exceeds 25 dB, and the radiation performance is stable with high efficiency. This antenna is particularly suitable for applications in 5G indoor communications.
