Parametric Modeling of Deformable Antennas Based on the Spherical Modes Expansion Method

Abstract : A parametric modeling procedure for analyzing the behavior of deformable antennas radiation characteristics is proposed in this article. This procedure is based on the vector spherical modes expansion method and on polynomial fitting of the coefficients. The methodology is applied to a canonical antenna – a bendable dipole – in order to demonstrate its performance. A deterministic model with high accuracy and high data compression rate up to 99.9% is derived.
