THEORETICAL STUDIES OF MICROSTRIP ANTENNAS. VOLUME I. GENERAL DESIGN TECHNIQUES AND ANALYSES OF SINGLE AND COUPLED ELEMENTS

Volume 1 of Theoretical Studies of Microstrip Antennas deals with general design techniques and analyses of single and coupled radiating elements. Specifically, we review and then employ an important equivalence theorem that allows a pair of vector potentials, A-bar and A-bar-star to be calculated from fields tangential to any surface enclosing all currents and charges. These potentials serve to calculate the far fields, from which radiation conductance and pattern can be obtained. For rectangular microstrip patch antennas, we develop novel approximations so as to include the effects of currents induced on the ground planes by fringing fields. Coupling between two patches sharing the same substrate and ground plane, or else employing separate ones stacked one above the other, is also considered by means of a novel approximation that helps provide physical insight with respect to field patterns, coupling between patches and the like. As an important by-product of this work, several new approximate formulas are obtained that very accurately predict the electrical characteristics of microstrip transmission lines of arbitrary width and substrate thickness when the dielectric constant of the substrate is also arbitrary. Volume II of this report is devoted to the analysis and synthesis of multiresonant elements with emphasis on dual-frequency operation of rectangular microstrip patch antennas with or without external matching networks.
