Planar Electromagnetic Band Gap For Broadband Switching Noise Mitigation In High-Speed Pcb, Kevin H. Nguyen
Planar Electromagnetic Band Gap For Broadband Switching Noise Mitigation In High-Speed Pcb, Kevin H. Nguyen
Theses and Dissertations
Electromagnetic band gap (EBG) structure with novel meandered lines for mitigation of simultaneous switching noise (SSN) from multiple switch mode power supplies on a high speed digital circuit card assembly is investigated. The electromagnetic band gap structure is designed for a wideband operation from 200 MHz to 15 GHz. The application interest for this planar structure can be used as high impedance surfaces to suppress EMI noise for EMC compliance in Mil-Std-461, which is an electromagnetic compatibility standard for military equipment operating in the frequency range from 10 KHz to 18 GHz. ANSYS HFSS was used for simulation of these …
