Abstract:
The present invention relates to a dielectric resonator antenna (DRA) with a transverse-rectangle well. The DRA comprising a substrate, a ground plane, a feed conductor, and a dielectric resonator. The resonator further includes a main body and a well penetrating the main body to enhance the electric field, to increase the radiation efficiency, to broaden the bandwidth, and to create new resonant mode. The DRA has the radiation pattern of broad beamwidth with vertical polarization. Accordingly, the invention can also be adjusted as WLAN 802.11a antenna.
