Abstract
In one embodiment, an antenna system performance metric for a tunable antenna system comprising tunable impedance elements is identified. The tunable impedance elements are simulated as uniquely numbered lumped ports characterizing a port network with a corresponding admittance or impedance matrix. The admittance or impedance matrix can be approximated using the periodicity of the tunable antenna system and the S-matrix of the port network can be estimated using the approximated admittance or impedance matrix. An optimal configuration of the tunable antenna system with respect to the antenna system performance metric is identified from responses of the tunable antenna system to variable impedances using the S-matrix. The optimal configuration of the tunable antenna system includes impedances of the tunable impedance elements modeled as the lumped ports in the port network.
