matlab code for an E-shaped antenna?

this is a matlab code for patch antenna,anybody can convert it to be usable code for an E-shaped antenna?.....please

S11 parameter code:

% plot reflection coefficient S11
figure
plot( freq/1e6, 20*log10(abs(s11)), 'k-', 'Linewidth', 2 );
grid on
title( 'reflection coefficient S_{11}' );
xlabel( 'frequency f / MHz' );
ylabel( 'reflection coefficient S_{11}' );

radiation pattern code:

% calculate the far field at phi=0 degrees and at phi=90 degrees 
disp( 'calculating far field at phi=[0 90] deg...' );
nf2ff = CalcNF2FF(nf2ff, Sim_Path, f_res, [-180:2:180]*pi/180, [0 90]*pi/180);

we have the full code for designing the patch antenna , if you want any other details please tell us.

can anybody please design E patch antenna using matlab? need very urgent

Antenna Toolbox already includes a built-in E-shaped patch antenna model (patchMicrostripEnotch). You can use it to analyze S11 (return loss), input impedance, and radiation patterns directly.

patchMicrostripEnotch - Create regular or AI-based probe-fed E-shaped microstrip patch antenna - MATLAB

Example:

ant = design(patchMicrostripEnotch,2e9);
figure,show(ant)
fiigure,pattern(ant,2e9)
