Abstract

This paper studied a design scheme and measurement results of circuit discontinuities on the basis of the recently proposed substrate integrated waveguide technology. Design considerations are discussed with respect to H-plane step, post resonator, 90° bend and 90° curvature, which are analyzed using an equivalent rectangular waveguide model. The results show a good agreement between design predictions and practical measurements will be compared within the paper was studied. Loss properties of the discontinuities are also examined. It is demonstrated that the radiation loss of the new substrate integrated waveguide is smaller as compared to dielectric and conductor losses. The boundaries of the SIW are realized by a series of a via holes, the size of which and distance between adjacent ones are determined by following a set of design rule. All simulation has been done by using Advanced Design System (ADS). To validate the theory and simulation, some of design has been fabricated and tested using Agilent analyser. All design has been realized by using a standard PCB process as a result, the cost of fabrication is cheap and reproducible.
