In this study, using a coplanar waveguide employing Periodic Strip Structure (PSS), highly miniaturized on-chip wilkinson power divider was realized on Si radio frequency integrated circuit (RFIC). The wilkinson power divider exhibited good RF performances from 25 to 50 GHz, and its size was $0.44{\times}0.1mm^2$, which is 4.8 % of conventional one. We also investigated the RF performances of various structures employing PSS.

In this work, we studied basic characteristics of transmission lines employing various PSS (periodic strip structure) on silicon substrate for application to a miniaturization of RF components. According to the results, the transmission lines employing various PSS showed wavelength shorter than conventional coplanar waveguide due to their strong wave characteristics. Especially, with-contact structure was most effective for a miniaturization of RF component. Concretely, the size of the transmission line employing with-contact was only 4.39 % of the conventional coplanar waveguide, According to the bandwidth extraction result, the bandwidth of the transmission lines employing various PSS structures were wider than 384 GHz. Above results indicate that the transmission lines employing various PSS can be effectively used for application to a broadband and miniature RF component, and especially, with-contact is most effective for a miniaturization of RF components.
