Radiated emission characteristics of oversized heat sinks that have surface area substantially larger than the top contact surface of the IC package are investigated. The oversized heat sinks are found to radiate higher levels at the frequencies that are present in components and traces in the proximity of the heat sink than the frequencies contained within the IC package itself. In this paper, oversized heat sinks are modeled as proximity coupled patch antennas with a short-circuited stub… CONTINUE READING
