Background
In the application of microwave systems, the solid rectangular waveguide and the coaxial transmission line are the most widely applied guided wave and transmission line systems at present, and the two transmission modes have better explanation effects. However, when the frequency of electromagnetic waves increases and the physical feature size of microwave transmission devices is scaled down, practical problems are encountered in high frequency systems, such as the need for solid rectangular waveguides with good conductive sidewalls and alignment to ensure good transmission of the electromagnetic waves, and the need for good electrical contact between separately fabricated parts even though strong walls are not required in some transmission configurations.
Microstrip lines and coplanar waveguide lines, on the other hand, are the most representative planar transmission lines, and they are robust, low-cost solutions well suited for integrating active microwave components on circuit boards. However, both of these planar transmission lines suffer from high dielectric loss in the millimeter-wave spectrum due to the presence of lossy dielectric materials, thereby causing transmission loss of electromagnetic waves.
