Equivalent Circuit Model of Comb-type Capacitive Transmission Line on MMIC for Application to the RF Component Design in Millimeter-Wave Wireless Communication System

摘要

In this work, the equivalent circuit of comb-type capacitive transmission line (CCTL) structure was investigated using theoretical analysis. The equivalent circuits for CCTL cell were extracted, and all lumped circuit parameters were expressed by closed-form equation. A fairly good agreement between calculated and measured results were observed up to 50 GHz. Above results indicate that the proposed equivalent circuit model can be efficiently used for application to millimeter-wave wireless communication system.
