  • Abstract
    A differentially fed rectangular dielectric resonator antenna (DRA) is studied using the finite-difference time-domain (FDTD) method. The fundamental TEm mode of the rectangular DRA is excited at 2.4 GHz, with a 10-dB differential impedance bandwidth (|Sdd11| < -10 dB) of ~ 10.4%. To verify the theory, measurements were carried out, and reasonable agreement between theory and experiment is obtained. The effects of the magnitude and phase imbalances on the DRA impedance and radiation pattern are investigated.
