Abstract :
A differentially fed reconfigurable dielectric resonator antenna (DRA) is studied. Loading with different capacitors or varactors supplied by reverse voltages, the differentially fed DRA can operate at the different resonated frequency discretely or continuously. The far-field characteristics at resonated frequencies are also investigated.
