A system for mitigating radio frequency interference includes a multiple patch antenna array including a multiplicity of patch antenna elements. The multiple patch antenna array is positioned relative to an interfering antenna such that signals from the interfering antenna cause interference with the multiple patch antenna array. The system also includes an auxiliary antenna positioned relative to the multiple patch antenna array. The system additionally includes a device to generate a spatial null in a direction to the interfering antenna from the multiple patch antenna array in response to a first signal from the auxiliary antenna and a second signal from the multiple patch antenna array. The first signal and the second signal are generated in response to a transmitted signal being received by the auxiliary antenna and the multiple patch antenna array. The spatial null permits simultaneous operation of the multiple patch antenna array and the interfering antenna.
