Abstract
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.
