First Claim
Patent Images
1. A wideband dielectric resonator monopole antenna, comprising:
- a resonator having a column structure, part of its exterior surface is coated with a conductive material, and has a connector formed at a bottom end thereof; and
a feed-in/feed-out component which is composed of a wire pattern coated or printed on a substrate, wherein the wire pattern comprises a grounding part, parallel slot lines and open-circuited slot lines, and defines a resonator foot-print region;
the grounding part is made of a conductive material, and the parallel slot lines and the open-circuited slot lines are the part of the wire pattern that the conductive material is removed;
the parallel slot lines are composed of two parallel slot lines;
the open-circuited slot lines are composed of two open-circuited slot lines, which are extended and bent from the ends of the parallel slot lines at the resonator foot-print region;
wherein the connector of the conductive layer electrically connects with the grounding part of said wire pattern of the feed-in/feed-out component.

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.
