Abstract
Circuit with flat electromagnetic band gap resonance structure, includes a plurality of flat units formed at a conductor layer; each flat unit spirally revolves inward from a first end to an internal point following a rotation direction, and spirally revolves outward from the internal point to a second end following an opposite rotation direction. Each flat unit is connected to a ground plane by a conductive stand (e.g., a via) at a connection point, for suppressing noise resonances at certain frequencies, and the frequencies are related to a stub length of each flat unit, and the stub length is related to a route length from the connection point to an end.
