“…Recent results show that angle diversity provides identical or more protection than space diversity and also has potential economic benefits [1]. In this method the effect of angle diversity under multipath propagation environments is based on the arrival at slightly different angles of the indirect delayed and direct waves [2]. In general, there are several techniques for implementation of angular diversity.…”

This paper presents a two element dielectric resonator antenna configuration, designed by using a magnetodielectric material, excited by single co-axial feeding technique, by keeping them at the both sides of the co-axial probe for achieving the angle diversity. This material has been designed such that its temperature coefficient value is -1.02ppm/°C, which is near to zero. The microwave dielectric constant (εr) and permeability (µr) are determined by Hakki-Coleman dielectric resonator method and Nicholson-Ross-Weir conversion technique and found to be 8.02 and 1.64 respectively. The designed antenna shows its radiation toward two directions 46° and 308° at the resonance frequency of 4.81GHz, hence can be utilised for angle diversity. The bandwidth of the antenna is 400MHz, which is suitable for the application of Radiolocation and Fixed Mobile & Satellite communication. The obtained gain on both radiated directions is 2.93 dB and 3.72 dB respectively. This proposed antenna has been fabricated and there is good agreement between the simulated and measured results.
