Hello, everyone.
I have got the x,y,z coordinates and MagE for a radiation pattern. But when I want to plot it in spherical coordinates using 'patternCustom' function, I found the pattern is incomplete.
I attaced the data and script here. Can someone help me?

Hi Lu,
I understand that you would like to know about the incomplete appearance of the radiation pattern plot generated by the function `patternCustom`.
This is because the radiation pattern’s magnitude data is available only for a limited set of ‘phi’ and ‘theta’ angles, resulting in gaps in the plot. To obtain a complete plot, the theta and phi values should span a continuous range.
Below, I have included a sample code that demonstrates how to generate a continuous set of theta and phi values for plotting the radiation pattern.
Theta=-179:3:180;
theta=repmat(Theta,1,60)'; % repeat along the columns
Phi=-89:3:90;
phi=repmat(Phi,120,1); %repeats along the rows
phi=phi(:); % reshapes the matrix into arrays
I=rand(length(theta),1); % generates a random number
patternCustom(I,theta(1:length(I)),phi(1:length(I)));
You can refer the following links to understand the functions used:
I hope this resolves your query.
