In the journals that I've read, they designed mimo antennas to be applied to mobile smartphones with 5G technology, i became interested to design mimo antenna with cst software. But, i had difficulties when trying to show the shape of antenna radiation pattern in various angles like in picture. I mean, I want to show the antenna radiation pattern I have designed with 3 angles like in the picture, angle 0 degree, 30 degree, and 60 degree. What should I do? In the journal I do not know what software they use.
CST should do this. You may need to generate the pictures separately for each scan angle and then paste the three views onto the same picture.
Thanks for your answer Sir. But, what i mean here that I want to show the antenna radiation pattern I have designed, with 3 angles like in the picture, angle 0 degree, 30 degree, and 60 degree in CST Microwave Studio software.
You need to feed the different antennas with different phases, so that the beam is pointed in the direction you want to point it. if you want it to point 30 degrees away from normal then the delay between antennas is sin 30 times the separation between them. You can turn this into phase by multiplying by the wavenumber k=2pi/wavelength or into time by dividing by the speed of light.

I guess what you need to do is feed the antennas with regular ports (discrete or waveguide) then after the simulation is finished you go to "combine results", there you have the choice to get the farfield patter for different arbitrary amplitude/phase at each port. Since the simulation is done already, this step is very fast.
@Marcelo B. Perotoni. Sir is it possible to simulate the antenna with phase by using simultaneous method which is done for 2 or more port antennas. Because when I do it I am getting error as attached file. Kindly can u help me.
