TY - JOUR A1 - Yeap, Kim Ho A1 - Meister, Tobias A1 - Oh, Zi Xin A1 - Nisar, Humaira T1 - Circuit Modelling Methodology for Dual-band Planar Antennas JF - APPLIED COMPUTATIONAL ELECTROMAGNETICS SOCIETY JOURNAL N2 - This paper presents a simple and systematic approach to determine the equivalent frequency-independent 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.
