A dual-band tri-element elliptical patch array antenna for WLAN access-points

In this paper a dual WLAN band, three elements circular patch array antenna with a novel radial tapered feed network introduced. Although the proposed antenna with back reflector has been chosen as main prototype for optimization, fabrication and test, observed that this antenna in without reflector mode can also operated with acceptable impedance performance in WLAN2.4/5.8GHz bands. In reflector mode, the proposed antenna recognize a band tunable antenna depend on the distance between of reflector plane and antenna.
