SYNTHESIS LECTURES ON ANTENNAS GENERALIZED TR...

This book gives a step-by-step presentation of a generalized transmission line method to study
the far-zone radiation of antennas under a multilayer structure. Normally  a radiation problem
requires a full wave analysis which may be time consuming. The beauty of the generalized
transmission line method is that it transforms the radiation problem for a specific type of
structure  say the multilayer structure excited by an antenna  into a circuit problem that can
be efficiently analyzed. Using the Reciprocity Theorem and far-field approximation  the method
computes the far-zone radiation due to a Hertzian dipole within a multilayer structure by
solving an equivalent transmission line circuit. Since an antenna can be modeled as a set of
Hertzian dipoles  the method could be used to predict the far-zone radiation of an antenna
under a multilayer structure. The analytical expression for the far-zone field is derived for a
structure with or without a polarizer. The procedure of obtaining the Hertzian dipole model
that is required by the generalized transmission line method is also described. Several
examples are given to demonstrate the capabilities  accuracy  and efficiency of this
method.Table of Contents: Antennas Under a Multilayer Dielectric Slab   Antennas Under a
