plot the polar pattern for a dipole antenna. select a suitable range of angles over which to plot. in matlab

main.m
theta = linspace(0, 2*pi, 360); % Define range of angles from 0 to 2*pi
Prad = 1; % Radiation power

% Calculate the normalized electric field at the far-field
E_theta = (cos(theta)).^2; 

% Calculate the directivity of the dipole
D = 3*(cos(theta)).^2;

% Calculate the radiation intensity
U = Prad*D/(4*pi);

% Plot the polar pattern
polarplot(theta, U)

% Display the plot
