Analysis of Sectorization Technique in Conventional Dielectric Resonators for Circular Polarization

The analysis presented in this article is based on the investigation of circular polarization (CP) performance in Dielectric Resonator Antennas (DRA) by use of their geometrical dimensions with simple probe feeding technique. The operating principle is based on detuning of degenerate modes and proper optimization of the sector angle $(\beta)$ which provides an extra context for better optimization of antenna performance as compared to conventional geometries. Sectorization method has been implemented for the first time in DRA technology for circular polarization analysis and corresponding physics is developed. The property of degenerate modes in DRA geometry has been explored for CP generation
