A Circularly Polarized Cylindrical Dielectric Resonator Antenna Using a Helical Exciter
2012 (English)Report (Other academic)
A novel circularly polarized cylindrical dielectric resonator antennaexcited by an external tape helix is presented. The helix is fed by a coaxialline through a small hole on a finite size ground plane. The configurationoffers a compact and easy to fabricate feeding network providing a 3 dBaxial-ratio bandwidth of 6.4%. A prototype of the proposed configurationis fabricated and measured. Measured and simulated return loss, axial-ratio and radiation pattern are presented and discussed together withdesign guidelines.
