摘要

本文介绍了一种基于带槽寄生贴片的圆极化（CP）滤波贴片天线。该结构由一个 CP 馈电网络、一个驱动贴片和两个寄生贴片组成。当引入带槽的寄生贴片时，会产生两个辐射空（RN），RN 的位置可通过槽的长度来控制。此外，与不带寄生贴片的天线相比，阻抗带宽和轴向比（AR）带宽都得到了改善。我们制作并测量了一个原型。阻抗带宽为 14.9% (3.42-3.97 GHz)，3-dB AR 带宽为 8.9% (3.53-3.86 GHz)。中心频率为 3.70 GHz 时的实现增益高达 8.1 dBiC。在 2.95 和 4.55 GHz 处产生了两个辐射空点。所提出的 CP 滤波天线具有结构简单、易于制造等优点，有望成为无线通信的理想选择。

A Circularly Polarized Filtering Patch Antenna Based on Parasitic Patches With Slots

A circularly polarized (CP) filtering patch antenna based on parasitic patches with slots is presented. The structure consists of one CP feeding network, one driven patch, and two parasitic patches. Two radiation nulls (RNs) are caused when the parasitic patches with slots are introduced, and the locations of RNs could be controlled by the slot length. Besides, the impedance bandwidth and axial ratio (AR) bandwidth are both improved compared to the antenna without parasitic patches. A prototype is fabricated and measured. The impedance bandwidth is 14.9% (3.42–3.97 GHz), and the 3-dB AR bandwidth is 8.9% (3.53–3.86 GHz). The realized gain at center frequency of 3.70 GHz is high up to 8.1 dBiC. Two radiation nulls at 2.95 and 4.55 GHz are generated. The proposed CP filtering antenna has the advantages of simple structure and easy fabrication, and can be a promising choice for wireless communications.
