A reconfigurable dielectric resonator antenna with pattern diversity for DVB-H application

A stacked-dielectric resonator antenna (S-DRA) with frequency reconfigurability and radiation pattern diversity is presented for DVB-H application. Two metallic patches are used that can be connected by RF switches to extend the ground plane. By extending the ground plane, pattern diversity and reconfigurability is achieved. This antenna offers reconfigurability from 0.47 GHz to 0.89 GHz for return loss below -10 dB. Performance in terms of return loss, current distributions, peak gain, radiation pattern and total efficiency of the designed antenna is presented that covers UHF band IV and V, respectively.
