In this paper we introduce an effective approach for dynamic impedance tuning of antennas in the transmission mode. The proposed approach is based on an optimization process that solves a system of two non-linear equations. It takes place in real-time and computes the actual input impedance of an antenna that changes in reaction to its environment. Our proposed approach does not limit the number of tunable components as the computational overhead is independent of their cardinality. Hence the proposed approach is efficiently applied for broadband antenna tuning.
