The characteristics of a microstrip transmission line with a finite-width curved substrate are investigated in this letter by first employing the fast and accurate finite-element boundary-integral method to simulate the current distribution, then using a superresolution estimation of signal parameters via the rotational invariance technique (ESPRIT) algorithm to extract the characteristic parameters of the transmission line. The validity of our simulation tool is confirmed by a comparison of our numerical results and previously published results. Radiation losses due to the finite width of the substrate are also-included in this letter.
