提出了一种宽带（1.71-2.17 GHz）、高隔离度和双极化悬置平板天线（SPA）。改进的L探针馈电用于宽带匹配和电容耦合。两个正交极化通道之间的端口隔离通过在悬置板（SP）上进行延伸并在第一SP（SP1）下插入垂直的不接地方管来改善。原型SPA产生8 ± 0.5 dBi增益和67° ± 6°对称E平面和H平面辐射方向图，交叉极化水平较低。在整个频带内，回波损耗≤−15 dB，端口隔离≤−30 dB。© 2015威利期刊公司.微波光学技术快报57：603-607，2015
A broadband (1.71–2.17 GHz), high isolation, and dual‐polarized suspended plate antenna (SPA) is presented. Modified L‐probe feed is used for broadband matching and capacitive coupling. Port isolation between two orthogonally polarized channels is improved by making extensions on suspended plates (SPs) and inserting a vertical ungrounded square tube under the first SP (SP1). The prototyped SPA resulted in 8 ± 0.5 dBi gain and 67° ± 6° symmetric E‐plane and H‐plane radiation patterns with low cross‐polarization levels. Return losses ≤−15 dB and port isolation ≤−30 dB are achieved in the entire band. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:603–607, 2015
