Investigation on Feeding Techniques for Rectangular Dielectric Resonator Antenna in Higher-Order Mode for 5G Applications

Abstract:

This paper presents the investigation on rectangular dielectric resonator antenna (RDRA) using three different feeding techniques that are microstrip slot aperture (MSA), microstrip line (ML) and open-end coplanar waveguide (OECPW). In order to increase the RDRA size and gain for 5G applications, the higher-order mode was used to excite the RDRA at the frequency resonant 28 GHz. Duroid dielectric substrate was used with a thickness of 0.254 mm, a permittivity of 2.2 and a loss tangent of 0.0009. Verification of the comparison was done by simulation using Ansoft HFSS. The simulated result for reflection coefficients, bandwidth, gain, radiation pattern and E-field strength was analyzed and compared.
