how to design a microstrip patch antenna using matlab ?

c = 3*10^8;

m = 1;

n = 1;

pp = 1;

E = 12.8;

a = 10*10^-3:0.1*10^-3:30*10^-3;

b = 10*10^-3;

d = 10*10^-3;

f = zeros(1,length(a));

for i=1:length(a)

f(i) = c/(2*pi)*sqrt(E)*sqrt(((m*pi)/a(i))^2+(n*pi/b)^2+(pp*pi/(2*d))^2);

end

a1 = 10*10^-3;

b1 = 10*10^-3:0.1*10^-3:30*10^-3;

d1 = 10*10^-3;

f1 = zeros(1,length(b1));

for k=1:length(b1)

f1(k) = c/(2*pi)*sqrt(E)*sqrt(((m*pi)/a1)^2+(n*pi/b1(k))^2+(pp*pi/(2*d1)^2));

end

a2 = 10*10^-3;

b2 = 10*10^-3;

d2 = 10*10^-3:0.1*10^-3:30*10^-3;

f2 = zeros(1,length(d2));

for t=1:length(d2)

f2(t) = c/(2*pi)*sqrt(E)*sqrt((m*pi)/a2)^2+(n*pi/b2)^2+(pp*pi/(2*d2(t)^2));

end

subplot(3,1,1);plot(a,f);title('plot a vs f when a is varying');

subplot(3,1,2);plot(b1,f);title('plot b vs f when b is varying');

subplot(3,1,3);plot(d2,f);title('plot d vs f when d is varying');
