Abstract :
A compact dual-polarized circular patch antenna with high isolation and low cross-polarization level for pico base station is presented. Stacked structure and dual-feed mechanism are employed in the design. Two slots around each feed point are cut on the lower patch to reduce the antenna size and enhance the bandwidth. The antenna occupies an area of 45mm×45mm and has a thickness of 5.5mm. Simulated results show that the proposed antenna achieves 7.3% bandwidth (VSWR<;1.4), operating between 2.5GHz and 2.69GHz. The isolation between the two polarized ports is more than 40 dB over the entire bandwidth. A stable low cross-polarization level of -40 dB is obtained in both the principle planes.
