Title:
METHOD AND APPARATUS TO CONTROL AN ANTENNA EFFICIENCY TEST DEVICE
Document Type and Number:
WIPO Patent Application WO2006007004
Kind Code:
A3
Abstract:
The present invention provides a method to measure antenna efficiency using the cavity method. In particular, the present invention provides a tunable cavity (104) that can be tuned to avoid the anti resonance and antenna-cavity coupling problems. In particular, tuning probes (108-1 and 108-2) and/or variable volumetric sizing of the cavity are used to tune the cavity to avoid the anti resonance and antenna-cavity coupling.
