Proposal for a SIW phase-inverter

Abstract

A substrate-integrated waveguide (SIW) phase-inverter is proposed that comprises a coplanar-waveguide (CPW) vertical interconnect, and a pair of SIW-to-CPW transitions. Similar to SIW, the structure requires two metal layers. Simulations of a SIW phase-inverter operating from 4 to 6 GHz demonstrate the feasibility of this approach.
