Design and implementation of a technology planar 8×8 Butler matrix with square truncated Edge-Fed array antenna for WLAN networks application

Abstract

In this paper switched beam smart antenna systems are investigated to improve the performance of wireless networks. The microstrip technology of antenna arrays with Butler matrix topology as a beam-former is used to implement the switched beam smart antenna system. The optimum design of a 8×8 planar Butler matrix array, operating at 2.4 GHz for WLAN applications. Systems design and optimization was based on computer simulations.
