Adaptive Antenna Array for Satellite Communication Systems

Satellite Communication Systems are beneficial in providing communication services to vast regions especially where the adequate infrastructure for communication may not be constructed. Wireless communication is one of the fastest growing fields in the engineering world. Introduction on adaptive antenna array is described in this paper. Linear adaptive algorithm LMS (Least mean square) is used to demonstrate the self-steering capability of an adaptive antenna array. It is done by changing number of elements in antenna array and angle of beam steering. The adaptive array has the ability to track the satellite automatically as it moves across the sky. MATLAB software has been used to obtain array voltage patterns for different values of number of elements in antenna array for different values of beam steering angle.
