Unsymmetrical dipole antenna

摘要

An unsymmetrical dipole antenna includes a grounding element, a radiating element, and a feed-in wire. The grounding element includes a first short side metal plane and a first long side metal plane. The radiating element includes a second short side metal plane and a second long side metal plane. The feed-in wire includes a metal wire, coupled to the second short side metal plane for transmitting a feed-in signal; an insulation layer, covering the metal wire; a metal weave, covering the insulation layer, having one terminal coupled to the first short side metal plane of the grounding element, and another terminal coupled to a system ground of the wireless communication device; and a protective layer, covering the metal weave. A size of the grounding element and a size of the radiating element are irrelative.

1. An unsymmetrical dipole antenna for a wireless communication device, comprising:
a feed terminal; a ground terminal; a grounding element, comprising:
a first short side metal plane, directly coupled to the ground terminal and extending from the ground terminal toward a first direction; anda first long side metal plane, coupled to the first short side metal plane, and extending from a first connection point with the first short side metal plane toward a second direction substantially perpendicular to the first direction; a radiating element, comprising:
a second short side metal plane, directly coupled to the feed terminal, separating from the first short side metal plane by a first distance, and extending from the feed terminal toward an opposite direction of the first direction; anda second long side metal plane, coupled to the second short side metal plane, and extending from a second connection point with the second short side metal plane toward the second direction; and a feed-in wire, comprising:
a metal wire, coupled to the second short side metal plane of the radiating element via the feed terminal, for transmitting a feed-in signal;an insulation layer, covering the metal wire;a metal weave, covering the insulation layer, having one terminal coupled to the first short side metal plane of the grounding element via the ground terminal and another terminal coupled to a system ground of the wireless communication device; anda protective layer, covering the metal weave; wherein the grounding element and the radiating element form an unsymmetrical dipole structure; wherein a length of the first short side metal plane and a length of the second short side metal plane are unequal, and a length of the first long side metal plane and a length of the second long side metal plane are unequal; wherein a total length of the first short side metal plane and the first long side metal plane and a total length of the second short side metal plane and the second long side metal plane are unequal.
