摘要：
A compact monopole antenna with broadband circular polarization for global navigation satellite system (GNSS) applications is presented in this paper. The proposed antenna comprises a simple tilted radiator fed by 50-Ohm microstrip line and an improved ground plane. By embedding two isosceles right triangular slits and introducing an isosceles right triangular perturbation in the ground plane, the circularly polarized (CP) performance can be improved significantly. The impedance and circular polarization characteristics are studied by simulation and measurement. With a compact size of 79 × 79 × 1.5mm3 for the fabricated antenna, a measured 10-dB return loss bandwidth of 35.6% (1.13–1.62 GHz) and a 3-dB AR bandwidth of 35.4% (1.14–1.63 GHz) can be achieved. © 2016, Electromagnetics Academy.
