This is the first of a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques.
This article discusses the distribution of a PCB return current underneath top trace for the microstrip configuration. Next month’s article will discuss the distribution for the stripline configurations.
This two-article series is devoted to a dipole family of antennas used in EMC testing: half-wave dipole, quarter-wave monopole, log-periodic, and biconical antenna. Part I presents the antenna models and the construction details.
This article discusses the origins, justification, and interrelations between some of basic EMC rules regarding the highest significant frequency (bandwidth) present in digital signals, definition of the electrically short structures, and the transmission line criterion.
