A basic polar plot tool in dB linear scale (Scripts) free download

Hi everyone,this is a basic polar plot tool in dB , you can change the range which can be very helpful for analyze the nature of your pattern.Here is a test code:%------------------------% Linear Arrays of Isotropic Elementsconst=1 lambda=1 k=2*pi/lambdatheta=linspace(0,2*pi,200)d=1/1*lambda % distance between the elementsI=ones(1,5) %Identical elementsAF=zeros(1,length(theta))%Array factor (rotational symmetry)for n=1:length(I)AF=AF+abs(I(n))*exp(1i*(n-1)*k*d*cos(theta))endAF=AF/max(AF) %normalf1=figure()set(f1,'Name','Simulation Plot for Linear Arrays of Isotropic Elements ')rangedb = 15 increments =3 rays = 12h=polar_dB(theta,AF,rangedb,increments,rays)
