• resonant frequency

Theoretical and experimental investigations on isosceles theta(i) - theta(i) - phi(i) triangular dielectric resonator antennas (TDRAs) are presented here for TM mode for the first time. Trilinear transformation is slightly modified to obtain the approximate solutions for eigenfunction and eigenvalue. Limitations of the theory are discussed. Closed form expression is given here to predict the resonant frequency with a maximum error of 4%. It is found that isosceles TDRA produces a peak in the broadside direction at fundamental TMz 101 and higher order TM103z modes. Three isosceles TDRAs having theta(i) = 60 degrees, 70 degrees, and 75 degrees are fabricated for experimental validation.
