Abstract

The full implementation of a slot-fed frequency-reconfigurable rectangular dielectric resonator antenna (DRA) is described. It uses two conducting walls, on opposite vertical faces of the DRA, which are switched via conducting tabs to be in contact or not with the groundplane. Theoretical and experimental performance results for such DRAs, using either PIN or varactor diode switches, are described, where prototypes were designed to operate between 3-8 GHz. The PIN diode-loaded and varactor-loaded DRAs achieved a tuning range of 91% and 55%, respectively, with other performance metrics detailed in the communication.
