Abstract

This paper reviews recent developments in automatic impedance matching and antenna tuning for wireless and mobile communications. UHF Tunable Matching Network (TMN) topologies are considered together with electronic device technologies for tuning a TMN and automatic tuning algorithms. Integrated Power Amplifier (PA) matching/antenna tuning, downlink (receive only) antenna tuning and antenna tuning for Multiple Input Multiple Output (MIMO) are also included.
