Description
Summary:In this paper, a partially dielectric-filled substrate integrated waveguide (PDF-SIW) configuration is analyzed for the frequency bandwidth and impedance matching to microstrip line. The PDF-SIW configuration may be designed for wider frequency bandwidth of the dominant TE 10 mode comparing to the homogeneous SIW. It is demonstrated that the propagation constant values computed for the PDF-SIW and for the equivalent partially dielectric-filled rectangular waveguide (PDF- RW) are practically the same, if the PDF-RW width is corrected based on a formula which is usually used for the homogeneous waveguides. It is also shown that the technique used to realize the transition from the homogeneous SIW to the microstrip line may be applied to realize the PDF-SIW to microstrip line transition, too.
