im trying to figure out where to add dipole radius and gap distance into this program below so i can plot the far field dipole
radition in the E-plane
i have this so far--v
%Wavelength
lam = .5;
%Dipole antanna
L = .68*lam;
%Phase constant
B = 2*pi/lam;
t = 0:0.01:2*pi;
% Far-field pattern equation
E2 = abs((cos(B*L/2*cos(t))-cos(B*L/2))./sin(t)).^2;
figure()
polar(t,E2)

You can use Antenna Toolbox to solve this using two lines of code
ant = design(dipole, 100e6);
pattern(ant, 100e6);
