Abstract

A theoretical investigation on radiation patterns of rectangular dielectric resonator antenna (RDRA) is presented. A simple model using magnetic walls (perfect and/or imperfect) and equivalence principle are utilized to predict the radiation patterns for TEmnp^y modes. Approximate solution for the eigenfunction is derived. Closed form expressions of radiation patterns are given. New broadside modes are also identified, hitherto unreported. Radiation Q-factor, gain and bandwidth are also described. Results are compared with measured data or data obtained using 3D EM simulator.
