Abstract :
The nonsymmetrically shielded coplanar waveguide (NSCPW) is proposed as a quasi-TEM (transverse electromagnetic) transmission line with advantageous characteristics for millimeter-wave circuit applications. The structure combines properties of the finline and the suspended stripline. In addition to a full-wave theoretical analysis, an experimental technique has been developed which enables the transmission line spectrum to be evaluated in a wide frequency band (15:1) with a single transmission measurement. Results are shown to be in excellent agreement with theoretical predictions. Design curves are also presented.<>
