Abstract

A novel microstrip antenna is presented for beam steering applications for 2.45 GHz (802.11b/g/n) WiFi band. The antenna consists of four L-shaped microstrips. Each L-shaped strip is fed by a vertical probe which is connected to a stepped transmission line impedance matching strip and other end of t...
