MULTI-BAND PRINTED MONOPOLE ANTENNA
First Claim
Patent Images
1. A multi-band antenna for an electronic device comprising:
- a substrate;
a ground portion disposed on the substrate;
a radiating portion disposed beside the ground portion; and
a feeder cable comprising a conductive inner core connecting with the radiating portion and a conductive outer shield connecting with the ground portion;
wherein the radiating portion electromagnetically couples with the ground portion to cause a first resonance in a first frequency band and causes a second resonance in a second frequency band.

Abstract
A multi-band printed monopole antenna (1) includes a substrate (2), a ground portion (4) disposed on the substrate, a radiating portion disposed beside the ground portion and a feeder cable (5). The radiating portion comprises a first and second radiating patches (31, 34) and a first and second connecting patches (32, 33). The second radiating patch resonances at a lower frequency band. A resonance slot formed between the first radiating patch and the ground portion for occurring a secondary resonance in a higher frequency band.

13. A multi-band antenna comprising:
-
a printed circuit board defining opposite first and second surfaces thereon, and thereof a short dimension along a vertical direction and a long dimension along a horizontal direction perpendicular to said vertical direction;
an L-shaped grounding portion disposed on the first surface and defining a long conductive patch along said vertical direction and a short conductive patch along said horizontal direction and perpendicular to said long conductive patch; and
a radiating portion disposed on said first surface and spatially beside said grounding portion, said radiating portion defining an elongated first radiating patch, for high frequencies, extending parallel to said long conductive patch and located in a rectangular area defined by said L-shaped grounding portion, and a second radiating patch, for low frequencies, extending parallel to said short conductive patch;
whereinsaid second radiating patch extends with most of said long dimension along said horizontal direction. - View Dependent Claims (14, 15, 16, 17)
