Abstract
With the rapid development of modern communication and radar technology, there is a need for the miniaturization, planarization, and modularization of microwave and millimeter-wave (mm-wave) systems, without losing excellent performance and reliability. The transmission line is the most basic component of microwave and mm-wave circuits and systems, and its characteristics-including loss, size, integration, cost, and weight-directly or indirectly affect the performance of the entire circuit and system. Commonly used transmission lines [1] include nonplanar transmission lines, such as a metal waveguide and coaxial line, and planar transmission lines, such as a microstrip, strip line, coplanar waveguide, and slot line.
