dc.description.abstractWe present a shunt capacitive substrate-integrated waveguide (SIW) discontinuity for the first time. The discontinuity is parametrically characterized in terms of its reactive impedance, and an equivalent circuit model is presented and validated. $C$ -band prototypes are manufactured and measured, confirming the simulated results. The utility of the discontinuity is then demonstrated as a part of a matching network for an $S$ -band amplifier. A simple synthesis method for the matching networks is presented, which requires minimal numerical optimization. The amplifier is prototyped and measured and found to be in good agreement with simulation.en_ZA
