Abstract
Provided is an Electromagnetic Bandgap (EBG) structure, particularly, a resonator and a bandpass filter having an overlay EBG structure, and a method of manufacturing the resonator. The resonator is manufactured by forming a transmission line and ground plates on a substrate, arranging a plurality of reflector units at regular intervals along the longitudinal direction of the transmission line, and removing at least one reflector among the plurality of reflectors, thus forming a common resonating mode. Therefore, since reflector units constructing capacitance components are separated from a substrate, it is possible to prevent electromagnetic waves from leaking out of the substrate and ensure a high Q characteristic in a high frequency environment due to a resonating unit formed between the reflector units.
