Design of Circularly Polarized Semi-Cylindrical Dielectric Resonator Antenna at Sub 6 GHz Frequency for 5G Applications

Abstract

A Semi-Cylindrical Dielectric Resonator Antenna (SCDRA) is designed to observe the radiation pattern and field distribution using boundary conditions. When the Semi-Cylindrical Dielectric Resonator antenna is fed with a coaxial probe, it makes a dielectric resonator antenna to increase the gain and directional radiation properties with circular polarization. It is observed that the antenna covers a bandwidth of sub-6 GHz frequency and radiates with an efficiency greater than 75% in the entire frequency band. The proposed semi-cylindrical dielectric resonator antenna can be used in 5th generation applications like emergency communications, fixed satellite communications, and smart devices.
