Band Gap Structure

In order to decrease the signal integrity problems caused by Simultaneous Switching Noise (SSN) in the high speed circuit, it has designed an improved planar electromagnetic band-gap (EBG) structure, which based on metamaterials. We want to model and simulate the stop-band characteristics by using the electromagnetic simulation software HFSS. The results show that, compared with the traditional UC-EBG structure, when the inhibition of depth is-30 dB, the bandwidth of this new type EBG of inhibition is 3.7 GHz, the upper cut-off frequency is 4.7 GHz, the lower cut-off frequency is 1 GHz, relative bandwidth is 130%.Compared with the traditional UC-EBG structure relative bandwidth increase 15%.
