CAD model to compute the resonant frequency of an equilateral triangular microstrip patch antenna including radome effect

Shifting of resonant frequency due to dielectric radome of a triangular microstrip antenna is theoretically investigated. A very simple, more accurate and more efficient CAD model is proposed in this paper. The computed values for wide range of variations of superstrate thickness and dielectric constant are compared with different theoretical and experimental values available in open literature and revealed close agreement.
