This work reports on a novel design of a compact and tunable filter in substrate integrated waveguide technology. The proposed dual‐band filter is based on resonators that exploit two resonating modes excited in a single SIW cavity. The structure is designed in such a way that the two bands of dual‐band filter each having two poles can be tuned independently. This property of the proposed filter makes it a suitable choice for multistandard applications with fine tuning as envisaged for future generation wireless technologies. The measured results of the fabricated prototypes validate the proposed design concept.
