Can any one give me the code for this plot (Radiation Pattern Hallen’s)

[Adam Danz]

These data are plotted on a polar plot.

Do you have a formula, or data?

As per my understanding you want to plot Hallen’s Radiation pattern. From the image I understand that the pattern looks like radiation pattern for dipole antenna

I would like to demonstrate it using below example

Antenna = design(dipole, 5000*1e6);
figure;
show(Antenna) 

 %%Antenna Analysis 
% Define plot frequency 
plotFrequency = 5*1e9;
% Define frequency range 
freqRange = (4500:50:5500)*1e6;
% Reference Impedance 
refImpedance = 50;
% Elevation
figure;
patternElevation(Antenna, plotFrequency,0,'Elevation',0:1:360);
