Abstract :
A broadband dielectric resonator (DR) antenna with an offset well is proposed. The well perturbs the original field distribution in the DR block to increase the impedance bandwidth associated with the mode. The feeding aperture generates a similar radiation pattern at adjacent band. The overall bandwidth covers the 5-6 GHz band of WLAN 802.11a.
