Investigation of a Right-Angled Isosceles Triangular Patch Antenna on Composite and Suspended Substrates Based on a CAD-Oriented Cavity Model

ABSTRACT In this article, a fast and accurate CAD-oriented cavity model and a single-resonant parallel R-L-C circuit has been proposed to predict the characteristics of a right-angled isosceles triangular patch antenna (RAITPA) on composite and suspended substrates. The accuracy of this model is computed against the experimental and HFSS computational results. The present model shows very close agreement with the experimental and HFSS computational results. To the best of our knowledge this is the first time that we have investigated a RAITPA on a composite substrate both theoretically and experimentally.
