Planar inverted F-type antenna |
摘要 |
An improved planar inverted F-type antenna comprises a metal ground plane having a feeding metal bore formed thereon, and a flat metal plate in parallel with the metal ground plane. The flat metal plate further includes an open circuit end and a short circuit end and provides a feeding leg to pass through the feeding metal bore. The short circuit end connects the metal ground plane through a short circuit leg. The distance between the open circuit end and short circuit end of the flat metal plate is proximate a quarter of wavelengths. The flat metal plate is formed as an open-short circuit trapezoid-shaped structure. The trapezoid-shaped structure increases operative bandwidth of the antenna.
