✦ Synopsis

The characteristics of a microstrip transmission line with a finite-width cur¨ed substrate are in¨estigated 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 ¨ia the rotational in¨ariance technique ( ) ESPRIT algorithm to extract the characteristic parameters of the transmission line. The ¨alidity of our simulation tool is confirmed by a comparison of our numerical results and pre¨iously published results. Radiation losses due to the finite width of the substrate are also included in this letter.

## Abstract The finite‐element method has been used for analyzing open microstrip line structures on highly lossy substrates. The geometry descritization has been carried out by using quadrilateral elements, and the spurious solutions are avoided by employing tangential vector formulation. The diff

## Abstract The distortion of a square pulse wave with a finite rise time in edge‐coupled microstrip lines is investigated. These microstrip lines are assumed to be fabricated on a single‐layer low‐temperature co‐fired ceramic (LTCC) substrate which has excellent high‐frequency performance. Paramet
