Abstract

This paper presents the design of an electronically steerable array antenna. An adaptive antenna using a slotted patch antenna for WLANs operated at 2.4 GHz is proposed. The designed antenna has five elements array, one for active elements and the remaining four are passive elements which connected to the variable reactance circuit. The variable reactance value will vary the beam pattern of the antenna. For the simulation, OFDM signal is used for the incoming signal and interference. Correlation between HGI and TGI is calculated as an objective function of the algorithm. A downhill simplex algorithm is used to maximize the cost function. From numerical simulation, null is performed for the incoming interference.
