Abstract :
A new method for back lobe suppression of microstrip patch antenna with a small ground is proposed and investigated for GPS receiver at 1.575 GHz. To reduce back lobe radiation, we use the slotted ground choke by etching slots on the corner of the ground plane. Experiment results show that the back lobe radiation is reduced lower than -35 dBi and the front-to-back ratio more than 40 dB.
