how to get the antenna efficiency in CST

Hi, is there anyone that knows how to get the antenna efficiency in CST? is it in the 1D result? but I cannot find it..... thanks in advance.

Define a far field monitor. Solve, Click on that in the results and you will get the efficiency.

1. Define farfield monitor
2. Run Transient Solver
3. Postprecess 1D - Farfield - Efficiency

it doesnt have efficiency just has directivity ,gain ,rcs,rcsw,power pattern .... no efficiency
