Closed form expressions for resonant frequency of rectangular patch antennas with multidielectric layers

Abstract

The conformal mapping approach combined with a generalized transmission line model has been developed to predict the resonant frequency of rectangular patch antennas with multidielectric layers. A set of closed form expressions is derived, which is suitable for direct application in CAD programs. Numerical results are presented to validate this method.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
