description Summary form only given, as follows. Phone output power and radiation efficiency are degraded by large mismatches, due to compact narrow-band antennas and influence of the user's hand position. This paper presents a 5 mm × 5 mm multi-band multi-mode adaptive tuning module that counteracts antenna impedance mismatch. The measured average total radiated power (TRP), of a commercially available phone with adaptive tuner, improves by 2.2 dB for free-space condition and 1.9 dB for user interaction with antenna.
