First Claim
Patent Images
1. A dielectric resonator antenna, comprising:
- a substrate, having a first surface and a second surface;
a ground plane, having a hollow portion and being formed on the first surface;
a feed conductor, formed on the second surface; and
a resonator of a dielectric material mounted on the ground plane, and further including;
a main body having a first side and a second side both vertical to the ground plane, and,a transverse-rectangular well formed in the main body, the well transversely penetrating through the first side and the second side, so that a portion of the main body becomes a lower horizontal wall defining the well, formed in between the well and the ground plane.

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.
