Abstract :
In this paper, we present the adaptive planar array for a 4-elements CPW fed-slot antenna to be used at WiMAX licensed band of 5.8 GHz by considering the mutual coupling effects. This method takes advantages of active element pattern that is achieved by full wave analysis of the array in Ansoft HFSS, obtaining complex weight by intelligent adaptive tracking controller based on motional learning model in mammalians brain. The control algorithm is provided with sensory input and reward signal which is independently searches for the proper control signal to be executed by actuators. We have used least mean square (LMS) algorithm to compare the results by brain emotional learning based intelligent controller (BELBIC).
