US 6,650,296 B2 · Dual-band monopole antenna

Abstract

A dual-band monopole antenna mainly comprises a microwave substrate, a first horizontal radiating metallic line, a second horizontal radiating metallic line, a vertical radiating metallic line, a feeding point, and a ground plane. The microwave substrate includes a first surface and a second surface. The first horizontal radiating metallic line is printed on the first surface. The second horizontal radiating metallic line is printed on the first surface. The vertical radiating metallic line is printed on the first surface, wherein the first horizontal radiating metallic line and the second horizontal radiating metallic line respectively intersect the vertical radiating metallic line at different positions. The feeding point is disposed on the vertical radiating metallic line, and a ground plane is printed on the second surface of the microwave substrate.

Dependent claims

A dual-band monopole antenna comprising:

a multiple-layer substrate having a first layer and a second layer, said second layer served as a ground plane with an empty region;
a plurality of radiating metallic lines arranged in substantially an “F” shape on said first layer and above said empty region for generating a first frequency band and a second frequency band, said plurality of radiating metallic lines having a first and a second radiating metallic lines substantially spaced apart, and a third radiating metallic line connected to said first and said second radiating metallic lines from the same side;
and
a feeding point located at a free end of said third radiating metallic line.
