Abstract

In this contribution, a quasi-analytical model is proposed allowing for fast characterization of a wide variety of printed transmission lines in terms of characteristic impedance, effective dielectric constant and losses. These losses are composed out of conductor losses, dielectric losses and radiation losses due to space and surface wave excitation. For printed transmission lines these latter losses are of particular importance when the transverse dimensions of the transmission lines become significant in terms of wavelength. The quasi-analytical model proposed in this thesis is implemented in a software tool, which is now rendered freely accessible, and capable of accurately analyzing the most widely used transmission lines. The software-tool can be downloaded at http://terahertz.tudelft.nl.
