Abstract

In this paper, a novel frequency splitter is proposed based on the spoof surface plasmon polaritons (SSPPs) coplanar waveguide (CPW). The proposed frequency splitter uses the semi-circular holes etched on the both sides of the middle line of the CPW to realize mode conversion and frequency splitting. The operating principles of the proposed frequency splitter have been analyzed by the dispersion curves, electric field distributions, and equivalent circuit. Moreover, the splitting frequency of the splitter can be easily controlled by changing the corresponding parameters. Furthermore, full-wave simulation along with the measured results are given to describe the performance of the proposed frequency splitter. The highly consistent between simulated and measured results validates the design conception, which means that the proposed design is of importance to develop surface-wave integrated circuits.
