Design, simulation and analysis of embedded Uni-planar compact electromagnetic band-gap structure

The design, simulation, analysis and application of embedded Uni-planar compact electromagnetic band-gap (E-UCEBG) structure for high speed digital circuit or mixed circuit application are presented in this paper. Shorting vias between shield plane and EBG plane are used to broaden the band-gap of E-UC-EBG. When the distance between the shorting vias is smaller than 1/8 wavelength of high stop frequency of band-gap, the E-UC-EBG can achieve comparable performance to the traditional UC-EBG. Signal integrity (SI) and electromagnetic compliance (EMC) of the E-UC-EBG are simulated and compared to those of the traditional UC-EBG. The results show that the E-UC-EBG can achieve better SI and EMC characteristic if designed properly. Two different simulators are used to verify the simulation results.
