An Early History of the Design and Development of the Dielectric Resonator Antenna

Almost 40 years after the initial development of the dielectric resonator antenna, a large number of variations based on the original design have been proposed, and some recently integrated into modern telecommunications equipment. As a class of radiators, they have been shown to be efficient at high frequencies with relatively large bandwidths. An early history of the design and development of this antenna is presented to document the processes which led to the original innovation.
