A method of inhibiting cross-polarization of a microstrip antenna and a device thereof. Increase of a microstrip antenna array not only increases co-polarization, but also increases cross-polarization. When the microstrip antenna is designed and fabricated, the fabricated antenna is tested first. That is, intensity distribution of the cross-polarization in a radiation frequency band is tested first, and a radiation frequency that the cross-polarization is corresponding change with is found out when an antenna radiation unit is broken. A slot is fabricated in the corresponding antenna radiation unit to break the symmetry of the antenna radiation unit, so as to effectively inhibit the cross-polarization without influencing the co-polarization of the antenna radiation unit at a corresponding radiation frequency.
