Are there any current RF products or applications where EBG structures are being used?
Not yet. EBG structures for noise suppression at the board and package level are still quite new. Most PCB and package designers are not aware of the possibilities. • Q: What are the software tools that traditionally simulate and analyze the PDN noise challenges which WEMTECs technology addresses? A: Software tools for power integrity analysis include SIwave from Ansoft, Power Si from Sigrity, and Power Grid from Apache. Other more general purpose electromagnetic analysis tools may also be used, such as 3D full-wave simulators from Ansoft and CST. • Q: Is the implementation of EBG structures into printed circuit boards something that can be done with standard PCB design and assembly processes, or would a new tool set need to be developed? A: Since WEMTEC EBG structures may be implemented as planar printed structures using conventional cores and metal layers, then standard layout tools such as those offered by Cadence or Mentor Graphics may be used for patch and via layout. Layout can b
