We propose a simple solution for jamming mitigation of L1 band GPS by electronically switching antenna beam for wide and narrow beamwidths.

Assuming the jamming signal is directed from low elevation angles, antenna reception can be made significantly lower at these angles by electronically reconfiguring the antenna beamwidth.

Four-element antenna array and one of the elements of the array are designated as antijam (array) mode and normal mode of the antenna.

The antenna is placed on a degenerate-ground with symmetric slots in the ground.

Front-end configuration for this antenna is also discussed.

Simulations and measurements are performed to validate the proposed design.

The antenna achieves more than 15 dB rejection in measurements and more than 20 dB cross-polarization improvement compared to standalone (normal mode) antenna.

The system can easily be replaced with existing active antenna to improve antijam capability of the receiver.
