TLM Modeling and System Identification of Distributed Microwave Circuits and Antennas

Abstract

In this paper we present the time domain computation of the impulse response of optimized antenna structures using the transmission line matrix TLM method. Hybrid extensions based on system identification (SI) are a means to reduce the computational burden considerably. Model-based SI procedures can be used to represent complex electromagnetic structures by means of both lumped element networks and distributed parameters models.
