Abstract: In this paper the conical shape reduced size microstrip patch antenna is connected to the reduced size butler matrix network and low cost smart antenna is form. This antenna is intermediate step between smart antenna and conventional antenna i.e. this antenna is cost effective solution for the smart antenna. Butler matrix network is used for beam switching. This design is realized on a low cost substrate FR4 with dielectric constant 4.4 and height of substrate is 1.6mm.Here antenna is operated at 2.4GHz frequency. The simulation result is obtained using HFSS.
