摘要：

A computer-aided design oriented cavity model is proposed in this article to predict the effect of composite and suspended substrates on the characteristics of an equilateral triangular patch antenna. The present model is very simple, fast, accurate, and valid for an entire range of permittivities and thicknesses of composite and suspended substrates as well as a single-substrate patch antenna. No design guide line or experimental results are available in the open literature to predict the characteristics of an equilateral triangular patch antenna on composite substrate. Also, the effect of a suspended substrate on input impedance, bandwidth, and gain of an equilateral triangular patch antenna has not yet been investigated, so commercial softwares (HFSS [Ansoft Corp., 2012] and CFDTD [Artech House, 2004]) was employed to validate the present model for a suspended and composite substrate triangular patch antenna. The computed values of a triangular patch on single substrate are compared with different theoretical and experimental values available in the open literature, and the present model shows very close agreements with the experimental results. This model is very useful for designing the microwave integrated circuit on semiconductor materials with epsilon(r) 10.
