摘要：
In this paper, a design for wideband and low cross polarization slot antenna at X band is presented. By adopting the double-layer slots and strip-line structure, the proposed antenna obtains a good characteristic of wide band. And unidirectional radiation is achieved by adding a planar reflector. In order to solve the weakness of high cross polarization and pattern distortion for wide slot antenna, an antiphase balanced feed network is introduced. Simulation results proved that the proposed antenna lowers the cross polarization level (XPL) while maintaining a bandwidth of 46.3% from 7.5GHz to 12.5GHz. The largest XPL in the range of half-power angle is -20dB. And the gain is 8.4dBi to 9.5dBi within the operating band.
