摘要：
This study presents an improved model for resonant frequency, input impedance, bandwidth and gain for a 30 degrees-60 degrees-90 degrees right angled triangular patch antenna printed on a single, composite and suspended substrate. Merits of this model include low computation cost and mathematical simplicity. It is useful for direct application in computer aided design (CAD) programs. The model is based on the classical methods: (i) the cavity model determining the resonant frequency and input resistance at resonance, (ii) the dynamic and effective permittivity to take into account the influence of fringing field at the edge of the patch and (iii) the equivalent resonant parallel R-L-C circuit for determination of input impedance. The present model shows very close agreements with the experimental and software computational results compared with the other models available in open literature for wide range of variation of antenna and substrate geometric and electrical parameters.
