Abstract
A resonant unit and a filter, where the resonant unit includes a dielectric substrate, a metal microstrip disposed on a plane of the dielectric substrate, where the metal microstrip is used as a signal input/output port, and a defected ground structure disposed on another plane opposite to the plane of the dielectric substrate, where the defected ground structure includes a ground loop and an interdigital structure located inside the ground loop, the interdigital structure includes multiple fingers, and the ground loop or at least one finger in the interdigital structure includes at least one embedded interdigital structure. Harmonic suppression capabilities of the resonant unit and the filter can be improved, and an area can be reduced.
