HFSS calculates directivity, gain, and power radiated, but I was wondering if I can measure them physically (without a simulator). If so, what equipment, technique, etc. is used for that?

Please reply ASAP as I have a presentation due soon.

Thanks

Yes, these parameters can be measured out. You can measure them in an Anechoic Chamber.

Thanks for reply. What equipment is used to measure these parameters? VNA? Please send links, docs that talks more about this.

One more thing: Can specific absorption rate (SAR) in head, for example, be measured? If so, how?

Thanks.

VNA is necessary, and you can search other equipments which are required on the internet. What I have are all in Chinese.
