Analysis of microstrip transmission-line on an anisotropic substrate

This paper addresses simple and straight solution of anisotropy. Dispersion & Characteristic Impedance play the vital role in modeling the circuit characteristics. For anisotropy, Equivalent isotropic relative permittivity epsiv_r,iso ^eq is the function of the physical dimension (w/h) of the Microstrip line. Several investigators have used different rigorous numerical solutions as Transmission-Line Matrix, Method of Moment, Fourier Series Techniques and SDA etc. to obtain expressions for the medium transformation. The proposed solution can be employed to compute the propagation characteristics of microstrip line at every anisotropic substrate materials. Two closed form models are valid for all practical and theoretical anisotropic materials (0.01 les w/h les15) with high frequency.
