摘要：
A broadband dual-polarized antenna fed by 50 ohm microstrip line is presented in this letter. The proposed antenna consists of four patches, two short pins and two feed structures. When two patches excite one polarized wave, the other patches are working as a parasitic structure. By the introduce of the short pins as a compensating component, the isolation and the cross polarization of the purposed antenna is improved. The proposed antenna achieves a 35.4% (3.9-5.6 GHz) relative bandwidth is achieved. Normalized cross polarization level is lower than -30 dB and isolation between ports is higher than 27 dB.
