Abstract: Some embodiments of the present disclosure relate to techniques for automatically measuring antenna mismatching conditions for a given mobile phone with a given antenna in a given environment and on a given frequency. In particular, some embodiments use a two way directional coupler coupled between a radio frequency (RF) transmitter output (e.g., analog front end) and an antenna tuner. This two-way directional coupler is coupled to a mismatch calculator, which is often implemented as a software algorithm, to accurately tune an antenna tuner to limit impedance mismatch. Consequently, changes in impedance mismatch can be tracked and compensated for so the user will not experience degradations in signal quality, thereby helping reduce the number of dropped calls, for example. Also, because power is tracked and radiated more accurately, these techniques save battery energy relative to conventional solutions and can stay on-line longer with optimum transmitting conditions.
