First Claim
Patent Images
1. A wideband dielectric resonator monopole antenna, comprising:
- a resonator having a column structure with an exterior surface, a conductive material coated on part of said exterior surface, and a connector extending downwards from the coated part of said exterior surface to a bottom end of said column structure; and
a feed-in/feed-out component composed of a wire pattern formed by coating or printing a conductive material on a substrate, said wire pattern having a grounding part formed with the conductive material of said wire pattern, and two parallel slot lines and two open-circuited slot lines formed without the conductive material of said wire pattern;
wherein each said open-circuited slot line is extended perpendicularly from an end of one said parallel slot line towards the other said parallel slot line with said two open-circuited slot lines located between said two parallel slot lines and separated by the conductive material of said wire pattern, and said resonator is disposed above said two open-circuited slot lines with said connector connected to said grounding part of said wire pattern.

Abstract
A wideband dielectric resonator monopole antenna, which includes a dielectric resonator and a monopole antenna, combines two frequency bands having close resonant frequencies to achieve 49% of bandwidth and omnidirectional radiation patterns within the frequency band. It includes a column structure and a substrate, wherein the surface of the column structure is coated with a conductive layer, the column structure is kept upright to the substrate, and the substrate is coated or printed with two slot lines extended inward from an edge of the substrate.
