Abstract

In this paper, a broadband dual-polarization slot antenna based on differential-feed at X band is proposed. By adopting wide round slots, the antenna inherits a good advantage of broad band. And the multi-layer structure achieves a good isolation between the two ports. In order to improve the high cross polarization level (XPL) and pattern distortion for wide slot antenna, differential feed is introduced. Simulation results shows that the proposed antenna obtains a 27% and 30% return loss bandwidth below -10 dB at each port respectively. The port isolation is below -20dB within the common band. The largest XPL in the range of half-power angle is -15dB. And the gain is 7.5dBi to 8.5dBi for port1 and 6.5dBi to 9.5dBi for port2.
