i simulated an antenna using cst mws, now i'm trying to plot the radiation pattern in matlab with CST data, data extracted from cst microwave studio was contain angle vs dB values. If I use polar command in matlab
polar(theta,rho)
I could not find the same polar plot as CST. Plz could u provide matlab code for radiation pattern in matlab.

Convert degrees to radians:
anglerad=deg2rad(angle);
polarplot(anglerad,db);
rlim([min(db) max(db)]);

As per my understanding you want to plot Radiation pattern from the data
I would like to demonstrate it using below example ,Here I saved your data in .xlsx file named Book1.
a = xlsread('L:\Book1.xlsx')
b=a(:,1);
c=a(:,2);
polarpattern(b,c);
