A conical cavity-backed antenna with embedded multiple quarter-wave resonators (multiple QWRs) is proposed. The 3-dB axial ratio bandwidth (ARBW) of a cavity-backed antenna is limited by cavity resonance, undesired cavity current, and circular polari

A design of circular ring reflector is presented to accomplish a high-gain antenna with circular polarization for GNSS application instead of using an LNA. The measured directivity reveals an enhancement of gain by back-lobe reduction. The reflection
