WIDEBAND CIRCULARLY POLARIZED HYBRID DIELECTRIC RESONATOR ANTENNA
First Claim
1. A dielectric resonator antenna comprising:
- a dielectric resonator;
a ground plane, operatively coupled with the dielectric resonator, the ground plane having four slots; and
a substrate, operatively coupled to the ground plane, having a feeding network consisting of four microstrip lines;
wherein the four slots are constructed and geometrically arranged to ensure proper circular polarization and coupling to the dielectric resonator; and
wherein the antenna feeding network combines the four microstrip lines with a 90 degree phase difference to generate circular polarization over a wide frequency band.
