We investigate the use of a reverberation chamber for the experimental measurement of deep implant antenna radiation efficiency. The technique was able to measure the extremely low efficiencies associated with deep implant antennas inside a muscle tissue-mimicking liquid phantom. Results were obtained for a range of insulated and un-insulated antennas with efficiencies as low as 0.06%. Analysis showed that while measurement errors were dominated by positioning variability, spurious feed cable radiation is still a significant factor that must be considered. Depending on the radiation characteristics of the antenna under test and the feed cable routing within the phantom, cable radiation could lead to errors of up to 4.5 dB.
