摘要：

This paper presents a slow-wave substrate integrated suspended parallel strip line (SW-SISPSL) for the first time. The slow-wave effect is produced by cascading high/low-impedance SISPSL in the meander line configuration. Different from conventional single-ended slow-wave transmission lines, the proposed SW-SISPSL supports differential signal transmission. The characteristic impedance and slow-wave factor of the SW-SISPSL are analyzed using equivalent circuit models. Using the proposed SW-SISPSL and a SISPSL phase inverter, a very compact rat-race coupler is implemented. The core circuit area of the slow-wave rat-race coupler is 0.083 & lambda;g x 0.089 & lambda;g, which is only 4.12% of the conventional topology.
