Design of rectangular dielectric resonator antenna using offset micro-strip feed for satellite application

This paper presents Rectangular Dielectric Resonator Antenna (RDRA) designed using Microstrip feed located at the edge of the RDRA i.e. Offset Location. Software package High Frequency Structure Simulator (HFSS) is used to simulate the antenna designs. Several designs are made considering different dimensions of the DRA (generally of dielectric constant=9.8) operating at different bands of frequency for S and C band applications. A change in frequency is observed due to the fringing effect in the DRA.
