摘要

本文提出了一种利用子结构特征模式实现三波段、双端口、双感圆极化微带贴片天线（MPA）的新设计方法。MPA由两个贴片层组成，在端口1下具有1.575 GHz和2.492 GHz左右的右圆极化（RHCP_）辐射图，而在端口2下也获得了1.615 GHz左右的左圆极化（LHCP）辐射图。最重要的是，保证了两个端口之间令人满意的隔离，表明所提出的MPA是北斗卫星导航系统（BDS）的优秀候选者。

Design of a Dual-Fed Triple-Band Circularly Polarized Microstrip Patch Antenna Using Substructure Characteristic Mode

In this letter, a novel design approach to achieve triple-band, dual-port, dual-sense circularly polarized microstrip patch antenna (MPA) is presented with the assistance of the substructure characteristic mode. The MPA consists of two patch layers, which have right-hand circularly polarized (RHCP_ radiation patterns around 1.575 GHz and 2.492 GHz under port 1, while the left-hand CP (LHCP) radiation pattern is also acquired around 1.615 GHz under port 2. Most importantly, the satisfactory isolation between the two ports is guaranteed, indicating that the proposed MPA is an excellent candidate for the BeiDou navigation satellite system (BDS).

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.
