摘要：
A compact dual-polarized antenna is presented and fabricated for wideband base station systems. A coupling ring is proposed surrounding two printed dipoles to earn low-profile property. Similarly, two baluns are loaded to excite the dipoles. By etching some semi-ellipses into baluns, a good impedance performance can be produced. These structures are manufactured on FR4 substrate and the entire dimension is small with a low-profile. Measured results show this antenna has a 36.7% impedance bandwidth (VSWR < 1.5) with a port isolation more than 30 dB. Furthermore, a peak gain of 7.8-11.3 dBi is achieved. Results show the proposed antenna has potential value to be further studied and used in Base station applications.
