Simulate near field antenna radiation pattern in CST Microwave Studio

Hello,

How can i simulate the near field radiation pattern of an antenna in CST?
I had try to search through the available field monitors that allow us to define, but seem like no near field monitor is provided.

Thank you.

Possible for me to get the E-field data around the antenna with a constant radius? For example like the E-field data for each theta value at Phi=0 degree.
