A miniaturized planar electromagnetic bandgap (EBG) structure with embedded meander line as bridge is proposed in this paper. The dimensions of the unit cell of the proposed EBG structure are 15 mm × 15 mm × 0.36 mm. Simulation and measurement of the noise transmission coefficient () have been performed for the structure, and good agreement can be seen. According to the measured results, the −30 dB noise suppression bandwidth ranges from 0.97 to 21.54 GHz, which cover almost the whole noise band in ultrawideband applications. Moreover, its effects on signal integrity and electromagnetic emission are also analyzed.
