Give the matlab code for the Plot of radiation pattern for linear arrays?

Answer 1

To plot the radiation pattern for linear arrays in MATLAB, you can use the following code snippet:

% Parameters
N = 8; % Number of elements
d = 0.5; % Element spacing (in wavelengths)
theta = linspace(0, 2*pi, 360); % Angle range

% Array factor calculation
AF = abs(sin(N*pi*d*sin(theta))./(sin(pi*d*sin(theta))));

% Plot
polarplot(theta, AF);

This code calculates the array factor for a linear array and plots the radiation pattern in polar coordinates. Adjust N and d as needed for different array configurations.
