Dual-band patch antenna with slot structure

摘要

A dual-band patch antenna with a slot structure is disclosed. The dual-band patch antenna comprises a metal-work antenna including a rectangular (patch) radiator on which an L-shaped slot structure is formed; two shorting strips and vertically shorted to a conductive ground plane formed on a base board; and a feeding means inserted into the base board. When the dual-band patch antenna is operated at about 2.45 GHz and about 5.4 GHz, good radiation pattern and antenna gain are obtained for being applicable to IEEE802.11b/g/a/j or Bluetooth specifications.
