Abstract
This paper proposes a circular polarization patch antenna for satellite communications that has the characteristic of rejecting the GPS and GLONASS frequency bands. The antenna is designed by applying a quadrangular complementary split ring resonator with negative values permeability to the antenna's ground plane. The circular polarization property is implemented in the antenna by truncating a comer of the patch. It is designed to reject the interferences which exist between the up-link and down-link frequencies utilizing the structure of the CSRR. This resonator which has the negative form of SRR is implemented on the rear part of the antenna's feed. Evaluation results demonstrate that the implemented antenna has a gain of approximately 0.2dB and an axial ratio of 3.6dB in the transmission frequency band and a gain of approximately 1,5dB and an axial ratio of3.1dB in the reception frequency band. It also fulfills the requirement of rejecting the GPS LI band and the GLONASS LI band. These results confirm that it is possible to design a circular polarization patch antenna with stop bands using CSRR.
