在这封信中，提出了一种具有平面馈电结构的四叶三叶草缝隙单元天线，用于双极化应用。设计了一个基于该天线的四元阵列，并进行了测试。该天线阵的馈电网络和辐射器在同一基板上，成本低，制作方便。两个极化的带宽分别为275和465 MHz。两个端口之间的隔离度大于30 dB，前后比大于25 dB。
In this letter, a four-leaf clover slot element antenna, which has a planar feeding structure, is proposed for dual-polarization applications. A four-element array based on the proposed antenna is designed and measured. The feeding network and radiators of the array are on the same substrate, which results in low-cost and convenient fabrication. The bandwidths of two polarizations are 275 and 465 MHz, respectively. The isolation between the two ports is greater than 30 dB, and the front-to-back ratio is higher than 25 dB.
