摘要： Provided is an electromagnetic bandgap (EBG) structure, and particularly, an overlay EBG structure in which a plurality of vias and a plurality of plates are formed at intervals on a central signal line in such a manner that the vias and plates extend vertically from a substrate in order to reduce leakage loss of an electromagnetic wave through the substrate. Therefore, it is possible to prevent an electromagnetic wave passing through a transmission line from being lost through the substrate, to obtain desired frequency characteristics by adjusting the dimensions of the vias and plates, and to manufacture the overlay EBG structure using an existing CMOS process without having to perform any additional process.

摘要： 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.

摘要： A broadband microstrip balun and a method of manufacturing the same are provided. In the balun, transmission lines formed at different layers partially overlap in parallel with each other, and a common ground having a predetermined opening is inserted between the transmission lines. Thus, an unbalanced signal may be converted into a balanced signal in a broad frequency band using resonance of a common ground plate with the opening and a Bethe hall effect. Also, impedance matching is readily enabled, thereby reducing a parasitic element.

摘要： A multilayered coplanar waveguide (CPW) filter unit and a method of manufacturing the same are provided. A plate having a capacitance element is formed on or below a CPW layer including a signal line for transmitting a signal and a ground plane. As the filter unit has a multilayered structure, characteristic impedance may be reduced without increasing the width of the signal line. Where an inductor line is inserted between the signal line and the plate, a clear frequency response curve may be obtained without performing an additional process or increasing the area of the filter unit.
