Patent ID: 8427337

Claim:
A planar dipole antenna comprising: a substrate; a ground element disposed on the substrate having a substantially rectangular shape; a feed point to which an input signal is supplied, the feed point being arranged adjacent to a side of the ground element; a matching element disposed on the substrate and connected to the feed point, the matching element comprising a central bar connected to a first arm and a second arm, wherein the central bar extends from the feed point, and the first and second arms are substantially symmetrically disposed on the substrate in respect to the central bar; a first radiating element disposed on the substrate having a substantially trapezoidal shape and connected to the matching element, the first radiating element extending from the first arm of the matching element; and a second radiating element disposed on the substrate having a substantially trapezoidal shape and connected to the matching element, the second radiating element extending from the second arm of the matching element, wherein the first radiating element and the second radiating element are substantially symmetrically disposed on the substrate in respect to the central bar of the matching element.
