Abstract: This study proposes an 4x4 planar microstrip array antenna with Butler matrix performing network can be used for a switched beam smart antenna system. The prototype antenna is operating in the ISM from 2.4-2.48 GHz for WLAN applications. The antenna is built on a FR4 substrate with relative permittivity of εr = 4.4, loss tangent of 0.02 and thickness of h = 1.6 mm. The performance of this smart antenna system was optimized and simulated by using commercially available full-wave, Method of Moment (MOM) based electromagnetic simulator Zeland IE3D.
