摘要：
A dualband dielectric resonator antenna (DRA) is designed by splitting a rectilinear dielectric resonator (DR) and carving notches off the DR. It is observed that notches engraved at different positions affect different modes. Removal of dielectric material from where the electric field is strong incurs a significant increase in resonant frequency. The abrupt change of normal electric field across the discontinuities reduces the Q-factor and increases the impedance bandwidth. Both the TE111y and TE113y modes incur broadside radiation patterns on the xy-plane. The proposed DRA can cover both the worldwide interoperability for,microwave access (WiMAX, 3.4-3.7-GHz) and the wireless local area network (WLAN, 5.15-5.35-GHz) bands.
