Combination of Full Wave Simulations and Equivalent Circuit Models in Predicting Coupling between Antenna Element and Nearby Object in Mobile Phone

Abstract

This paper presents a simple method for using data from full wave simulations in combination with lumped circuit models for calculating port responses for arbitrary loading and excitation conditions. Data from full wave simulations are used for constructing a matrix representation of port responses that is used in a circuit simulator code where arbitrary active and passive components can be added to the circuit. By this it is possible to evaluate different circuit configurations efficiently without the need of performing additional full wave simulations.
