open hfss, move to the left side of the screen..look for "project manager".
- then go for hfss design under your project manager tab..
- look for radiation at the last.. expand it..look for infinite sphere..
- click on infinite sphere..then click "compute antenna parameters".
u r done..
or else, please try the conventional formula available, taking the parameters data available from hfss

Of course, it is very easy to obtain the antenna radiation efficiency.
You can derive it from the antenna radiation parameters.

You can try to use Calculator (based on fields, voltages, current etc) available in HFSS, if you have the formula. But otherwise there is only Radiation efficiency directly available in HFSS.

Dear Md Samsuzzaman ;
You can check radiation efficiency through formula, gain and directivity relation, if you want directly the radiation efficiency then in project manager of hfss there will be a radiation open it when your infosphere or your intended sphere, go to compute antenna parameters with your operating frequency, it shows the radiation efficiency along with various parameters.
Thanks,

Dear Md Samsuzzaman ,
you can directly plot the radiation efficiency in hfss.

Open HFSS of your design and simulate,then go to result and follow the procedure. Results>create far field>rectangular plot>antenna parameters>radiation efficiency >absolute.It must be frequency Vs Radiation eff.

WHAT ABOUT WHEELER CAP METHOD FOR EFFICIENCY
Anil Kumar Nayak
Indian Institute of Technology Roorkee
The Wheeler Cap method is using for measurement of efficiency of an antenna.Not need for simulation.
Use this paper: H.A.Wheeler,“The radationsphere around a small antenna”,Proc.IRE,47 (8)pp.1325-1221,1975

NAYAK SIR HOW WE CALCULATE EFFICIENCY IN SIMULATION
Anil Kumar Nayak
Indian Institute of Technology Roorkee
Directly we calculate antenna efficiency from HFSS and CST,
First go to the result->Create far field report->Rectangular plot then follow the procedure and find the attached file

THANKS NAYAK JI, THIS METHOD IS OK. HOW WE TAKE THETA AND PHI AS 0 DEGREE, ANY REASON
Anil Kumar Nayak
Indian Institute of Technology Roorkee
If we designed E-plane antenna-ominidirectional (Patch/slot and etc) chose Phi=0 and for H-plane -directional ( Phi=90).But theta keep constant(0).
