In the paper, a 2.4GHz/5.8GHz compact rectangular ring and rectangular patch stacked shorted high gain antenna will be designed. The dual-band antenna’s resonator frequency are 2.4GHz and 5.8GHz. It’ impedance bandwidth achieve 12.5%. The maximum gain come to 10dBi. Neither indoor or outdoor, it can support WLAN (802.11a and 80.11g)
