Abstract :
A critical study of the resonant frequency of the equilateral triangular patch antenna is presented. The contributions include: (1) comparison of the previous experimental data of J. S. Dahele and K. F. Lee (see ibid., vol.AP-35, no.1, p.100-1, 1987) with moment method results; (2) new measurements and moment method results for εr=10.5 and comparison with Gang´s hypothesis; (3) verification of the relationship among the various modes by measurements and by the moment method; and (4) a curve fitting formula yielding the resonant frequency of the lowest mode, which is within 1% of the value obtained from moment method analysis
