Patent abstract

A dual-band patch antenna is disclosed. The dual-band patch antenna includes a polygon patch constructed from two rectangular radiators (radiating metal patches) combined as the shape similar to Siamese Twins, each of the rectangular radiators having a shorting strip for size reducing. The dual-band patch antenna employs one single common probe feed connected to the overlap portion of two rectangular radiators. 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.
