Patent Images
1. An antenna, comprising:
- a ground plane, having a reflection area, wherein a first side edge of the reflection area is aligned with an edge of the ground plane;
a radiation element, disposed near the first side edge of the reflection area and operated at a resonant frequency, wherein a width of the reflection area is related to a wavelength of the resonant frequency; and
a frequency selective structure, disposed on the ground plane along side edges of the reflection area except the first side edge, and adapted to reflect an electromagnetic wave from the radiation element.

Abstract
An antenna including a ground plane, a radiation element and a frequency selective structure is provided. The ground plane has a reflection area, and a first side edge of the reflection area is aligned with an edge of the ground plane. The radiation element is disposed near the first side edge of the reflection area and is operated at a resonant frequency. A width of the reflection area is related to a wavelength of the resonant frequency of the radiation element. The frequency selective structure is disposed on the ground plane along side edges of the reflection area except the first side edge and is adapted to reflect an electromagnetic wave from the radiation element.
