Summary:
This paper presents a wide band rectangular dielectric resonator antenna (DRA) with microstrip slot excitation valid for S frequency band applications. The resonant frequency and radiation Q-factor of the lowest order "magnetic dipole" mode are obtained using dielectric waveguide model with magnetic walls. The accuracy of the model in predicting the resonant frequency is verified by comparing the obtained results using FDTD numerical technique, with those of a ready made software based on finite element method. The paper also includes comparison between DRA and microstrip patch antenna, MPA, designed for the same range of frequency, and using the same feeding system which is aperture coupling microstrip line
