Abstract
The present invention provides a method to measure antenna efficiency using the cavity method. In particular, the present invention provides a tunable cavity that can be tuned to avoid the anti resonance and antenna-cavity coupling problems. In particular, tuning probes and/or variable volumetric sizing of the cavity are used to tune the cavity to avoid the anti resonance and antenna-cavity coupling.
