Dual band antenna
First Claim
1. A dual band antenna comprising:
- a conductive element comprising a first radiating portion, a second radiating portion, a ground portion, and a connection portion interconnecting the first and the second radiating portions with the ground portion, the connection portion comprising a first segment, a third segment, and a second segment interconnecting the first and the third segments, the first segment extending from a joint of the first and the second radiating portions, and the third segment connecting with the ground portion; and
a feeder cable electrically connecting to the conductive element.

Abstract
A dual band antenna (1) includes a planar conductive element and a feeder cable (6) electrically connecting to the conductive element. The conductive element includes a first radiating strip (2), a second radiating strip (3), a ground portion (5), and a connection strip (4) interconnecting the first and the second radiating strips with the ground portion. The first radiating strip and the connection strip are configured to function as a first planar inverted-F antenna (PIFA) operating in a higher frequency band. The second radiating strip and the connection strip are configured to function as a second PIFA operating in a lower frequency band. The first and the second radiating strip, the ground portion and the connection strip are all disposed in the same plane.

9. A dual band antenna comprising:
-
a planar conductive element including;
a large grounding portion;
a strip-like radiation portion extending in a first direction and parallel to said grounding portion; and
a lying Z-like connection portion with two opposite ends connected to said radiation portion and said grounding portion, respectively, said Z-like connection portion including a first segment and a second segment both extending in a second direction perpendicular to said first direction and connected with each other via a third segment; and
a feeder cable including an outer braiding connected to said grounding portion and an inner conductor connected to a position of said third segment along said first direction. - View Dependent Claims (10, 11)
