Theoretical and experimental investigations on isosceles <inline-formula> <tex-math notation="LaTeX">$\theta _{i}-\theta _{i}-\varphi _{i}$ </tex-math></inline-formula> 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 <inline-formula> <tex-math notation="LaTeX">$\text{TM}_{101}^{ {z}}$ </tex-math></inline-formula> and higher order <inline-formula> <tex-math notation="LaTeX">$\text{TM}_{103}^{ {z}}$ </tex-math></inline-formula> modes. Three isosceles TDRAs having <inline-formula> <tex-math notation="LaTeX">$\theta _{i}= 60^{\circ }$ </tex-math></inline-formula>, 70°, and 75° are fabricated<inline-formula> <tex-math notation="LaTeX">$\vphantom {^{\int }}$ </tex-math></inline-formula> for experimental validation.
