Dielectric and width effect on<tex>H</tex>-plane and<tex>E</tex>-plane coupling between rectangular microstrip antennas

Abstract

Theory and numerically computed results are presented for mutual coupling between two rectangular microstrip antenna patches. <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</tex> -plane alignment and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">H</tex> -plane alignment are the two patch orientations considered. The <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</tex> -parameter matrix element <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s_{11}</tex> is used to study the mutual coupling. Extensive results are provided for <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s_{11}</tex> covering several relative substrate dielectric constants, antenna patch widths, and antenna patch separations. Results are also given for resonant frequency, resonant impedance behavior, and radiation pattern at resonance.
