AN EFFICIENT ICT METHOD FOR ANALYSIS OF COPLANAR DIPOLE ANTENNA-ARRAYS OF ARBITRARY LENGTHS

A more judicious choice of trial functions to implement the Improved C ircuit Theory (ICT) application to multielement antennas is achieved. These new trial functions, based on Tai's modified variational impleme ntation for single element antennas, leads to an ICT implementation ap plicable to much longer co-planar dipole arrays. The accuracy of the g eneralized impedance formulas is in good agreement with the method of moments. Moreover, all these generalized formulas including the radiat ion pattern expressions are all in closed-form. This leads to an ICT i mplementation which still requires much shorter CPU time and lesser co mputer storage compared to method of moments. Thus, for co-planar dipo le arrays, the proposed implementation presents a relatively very effi cient method and would therefore be found useful in applications such as CAD/CAE systems.
