Antenna,Matlab

Write a Matlab code that ask the user to input the following data : 1. Number of elements within linear array (N). 2. Space (d) between the array elements. 3. Interelement phase shift B. The code should be able to: a) Plot the array factor AF(X) b) Plot the polar form of the antenna radiation pattern. Run your code and show the resulted graphs for the following 3 cases : 1) N=6, d=0.52, B = 0 2) N=6, d=0.52, B = 1200 3) N = 6, d=0.252, B = 120
