Plot radiation pattern of 2 antennas omnidirectional.

Hello to all the community.

I would get the radiation pattern in 3D produced by the 'array' of two omnidirectional antennas with 5dBi gain, separate 10 centimeters between them and with no offset. The antennas are this.

I would also represent the radiation pattern of one antenna 5dBi, to compare it with that obtained by putting together the two antennas.

Thank you very much in advance.

A greeting.

Can someone help me? How could represent the radiation pattern of a single omnidirectional antenna?

What should I do to get the two antennas?

Thank you

Well, there doesn't seem to be a Matlab specific question in there.

What have you tried so far?

One of the reasons why you haven't received any help might be that this looks suspiciously like homework or a job that you are dumping on volunteers.
