Multi-band antenna with wide bandwidth
First Claim
1. A built-in antenna used with an electronic device, comprising:
- a grounding portion;
a radiating portion arranged in a lengthwise direction and comprising adjacent first and second edges, the radiating portion defining at least two slots each having an open end respectively arranged on said first and second edges; and
a connecting portion connecting the radiating portion and the grounding portion, wherein the connecting portion comprises a first, a second and a third connecting sections corporately forming an n-shape with a slot therein for using to turn an impedance matching of the antenna.

Abstract
A multi-band antenna (100) used in wireless communications includes a first radiating patch (20) arranged in a first plane and extending in a first direction, a second radiating patch (22) arranged in the first plane and extending in a second direction different from the first direction, a grounding portion (1) arranged in second plane parallel to the first plane, and an inverted F-shaped connecting portion (3) connecting the first and the second radiating patches and the grounding portion. The radiating patches define a plurality of slots (201, 202) for increasing a bandwidth of the antenna. The connecting portion defines a rectangular slot (35) for adjusting an impedance matching of the antenna.
