A low‐profile dual‐polarized antenna with crosspolarization enhancement

摘要

Abstract > A dual‐polarized antenna that simultaneously achieves low profile, low crosspolarization, and high isolation is presented in this article. Our research indicates that the irregular currents on the artificial magnetic conductor (AMC) surface in our design can lead to an extra coupling. Because short pins can regularize the surface currents on the AMC surface and work as a balun, our antenna can achieve low crosspolarization and high port isolation. The proposed antenna achieves a profile height of 0.08 <fi>λ</fi> <sub>0</sub> ( <fi>λ</fi> <sub>0</sub> represents the wavelength in free space at 3.4 GHz) and 23.5% (3.0‐3.8 GHz) relative bandwidth. The port isolation of the presented antenna is higher than 37?dB and the normalized crosspolarization is lower than ?35?dB. The proposed antenna is suitable for the fifth generation communication systems. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div

本文提出了一种双极化天线，其同时实现低型材，低通散和高隔离。我们的研究表明，我们设计中人工磁导体（AMC）表面上的不规则电流可导致额外的耦合。由于短引脚可以规则地规范AMC表面上的表面电流并作为不平衡的工平，我们的天线可以实现低的十字极化和高端口隔离。所提出的天线达到0.08的轮廓高度 <fi>λ</ fi> <sub> 0 </ sub> （ <fi>λ</ fi> <sub> 0 </
