anybody has matlab code or any program to plot radiation pattern of different types of antennas (dipole,...)
both 3d and in the planes xy,yz,xz,... or any other plane

I want to find an equation which can describe the radiation pattern of an arbritary monopole. I want to use this equation to plot the 3-D radiation pattern in matlab.
I also want to investigate the difference in radiation pattern when the monopole (...)

You should check the matlab command you used for plot. The color usually is according to the Z value by default, rather the distance from the origin as you expect.

Yes, you can do it by using matlab,I've tried and I think that it works. If I understood well you want to plot your E-field or H-field or Gain (it is the same) as a function of phi and theta. you just have to plot A=f(theta,phi) what I suggest is to tranform your funtion in xyz coordinate system and then plot A as (...)

I've made a 2x2 aperture coupled microstrip antenna array. I have the S-params of each antenna element, and also of the corporate feed.
I cascaded them in Sonnet with Netlist. The resulting plot is a S11 plot.
I'd also like to get the radiation pattern. Do you know how I can get this?
I've heard I can (...)

you can use polar plot available in excel/matlab or if your simulation software imports txt file you can use that too!

plotting polar patterns in matlab could be proved very tricky ;)
matlab converts negative numbers to positive/180phase... 2D polar patterns need to be carefully converted before plotting...
Moreover, 3D polar patterns are impossible with matlab... You (...)

Who said you cannot with dB values. you have to do a scaling of the dB scale in order to plot.like this i dont have matlab installed on my new puppy ,old one crashed otherwise i would've shown you how.but for time being consider this
and fit yours into the above .you do a 40 Db adjustment because log of negative value

hi guys !!
how can i integrate this function in matlab ? E=(cos(2×pi×cos(θ)) - 1) /sin(θ)
also , how can i plot the (RP) radiation pattern of an antenna in 3D ...
where ; RP = =((cos(2×pi×cos(θ)) - 1) /sin(θ))^2
thank u !!!

Why would you want to simulate an antenna when you already have the pattern?
Knowing the close formula, i would use matlab to plot the pattern.
