Abstract :
The radiation pattern in the H-plane of smart antenna arrays (SAA), which includes the effects of mutual coupling (MC) is examined. In an SAA the effects of MC and nonuniform spacing between the array elements are compensated with the use of a transformation matrix T. The weight vector of the array is updated by way of the least-mean-square (LMS) algorithm. A MatLab program was developed to verify the MC for a smart antenna array.
