TLDR
In this paper, it was shown that the electric surface currents on the conducting patch of a microstrip antenna are equivalent to those produced by a magnetic surface current sheet bounding the patch in the substrate only when dyadic Green's functions for the two-layer stratified medium are used.Abstract:

A Dynamical Radiation Model for Microstrip Structures
Juan R. Mosig,Fred E. Gardiol +1 more
TL;DR: The chapter concludes the model is that the surface currents on the antenna are directly determined and the near field can then be determined easily, that becomes most important when microstrip structures are utilized as radiators or biological applicators.

A broad-band annular-ring microstrip antenna
TL;DR: In this paper, a heuristic discussion of the radiation properties of the transverse magnetic (TM 11 ) and (TM 12 ) modes of the annular-ring microstrip antenna is presented.

Electric surface current model for the analysis of microstrip antennas with application to rectangular elements
TL;DR: In this paper, an approach to the analysis of microstrip antennas which is applicable also to relatively thick substrates using the relevant Green's function is presented and closed form expressions for various antenna characteristics which explicitly take into account the presence of the dielectric material are obtained in terms of the electric surface current density.

On slot-coupled microstrip antennas and their applications to CP operation-theory and experiment
TL;DR: In this article, a simple theory based on the cavity model was developed to analyze microstrip antennas excited by a slot in the ground plane, and the loci of the slot feed location for achieving the circular polarization and the input impedance were computed and found to be in excellent agreement with the experimentally measured results.
Journal ArticleDOI
A comparison of CAD models for radiation from rectangular microstrip patches
TL;DR: In this article, the dominant mode electric current model and magnetic current model are each applied to the cases of a rectangular patch on an infinite substrate, and a patch on a substrate which is truncated at the edges of the patch.

Theory and experiment on microstrip antennas
Y.T. Lo,D. Solomon,W. Richards +2 more
TL;DR: In this article, a simple theory based on the cavity model was developed to analyze microstrip antennas, and the theoretically predicted radiation patterns and impedance loci closely agree with those measured for many antennas of various shapes and dimensions investigated thus far.

Microwave thermal emission from a stratified medium with nonuniform temperature distribution
TL;DR: In this paper, the brightness temperature of a stratified medium with inhomogeneous permittivities and non-uniform temperature profiles is solved using the dissipation-fluctuation approach.

Radiation characteristics of a circular microstrip antenna
TL;DR: In this article, the authors calculated the radiation patterns of a circular microstrip antenna with Green's functions for a two-layer medium and compared with previous results which are valid for thin slabs and small dielectric constants.

Theory of the circular-disc printed-circuit antenna
TL;DR: In this paper, a planar conducting structure, an electrically small distance above a ground plane, can be constructed to radiate in the direction normal to its plane while still retaining its low profile characteristics.
