摘要

本文提出了一种金属壁可重构毫米波（MMW）极化/辐射方向图可重构多输入多输出（MIMO）腔天线。首先，在同一腔内激发不同的模态。然后，利用金属壁来调节这些模式，单个狭缝允许线偏振，交叉狭缝允许圆偏振，从而可以动态控制偏振和辐射方向。最后，制作了工作在28.2 GHz中心频率的MIMO天线样机并进行了测试。在这两种状态下，都能实现良好的隔离和增益，使其适用于毫米波无线通信系统。

Circularly/Linearly Polarized and Pattern-Reconfigurable MIMO Millimeter-Wave Antenna

In this letter, a metal wall reconfigurable millimeter-wave (MMW) polarization/radiation pattern-reconfigurable multiple-input–multiple-output (MIMO) cavity antenna is presented. First, different modes are excited within the same cavity. Then, the metal wall is used to adjust these modes, with a single slot enabling linear polarization and a crossed slot enabling circular polarization, allowing dynamic control of both polarization and radiation direction. Finally, a MIMO antenna prototype operating at a center frequency of 28.2 GHz is fabricated and tested. In both states, good isolation and gain are achieved, making it suitable for millimeter-wave wireless communication systems.

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.
