Circularly Polarized High-gain Patch Antenna Using Higher-order Mode for GPS Applications

초록

This paper proposes a circularly polarized high-gain patch antenna for GPS applications. The CP radiation pattern is theoretically obtained by summing E-fields of \mathrm{TM}{030}{x} and \mathrm{TM}{003}{x} modes with a phase difference of 90°. To verify the design obtained based on the cavity model theory, we fabricate and measure the proposed antenna. The measured and simulated reflection coefficients are less than-13.3dB at 1.7 GHz. In addition, the measured and simulated bore-sight gains are 9.9 dBic and 10.6 dBic, respectively. © 2022 IEEE.
