Circuit Modelling Methodology for Dual-band Planar Antennas
Keywords:Data-fitting algorithm, equivalent circuit, Foster canonical network, planar antenna, resonant bands
This paper presents a simple and systematic approach to determine the equivalent frequencyindependent circuit model for a dual-band planar antenna. The Foster Canonical network synthesis technique with two RLC tanks has been employed to generate the two resonant bands of the antenna. The transfer function model is subsequently refined using a data fitting algorithm (viz the Nelder-Mead simplex algorithm). Parametric adjustments are performed at the final stage in order to further improve the accuracy of the final parameters.
