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 first and the second radiating portions, the ground portion and the connection portion being all arranged in a same plane; 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)

12. 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 opposite first and second ends connected to said radiation portion and said grounding portion, respectively, said Z-like connection portion including a first segment and a second segment 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;
wherein said first end divides said radiation portion into two unequal sections so as to formed two PIFAs back to back arranged with each other.
