A pair of differential signal lines implemented as strip lines are within the signaling layer, and propagate electromagnetic interference (EMI) along the signaling layer. An element conductively extends inwards from the exterior layer. A void of a defected ground structure within the ground layer has a size, shape, and a location in relation to the element to suppress the EMI propagated by the strip lines. A resistive material of the defected ground structure along a perimeter of the void improves suppression of the EMI propagated by the strip lines, via the resistive material absorbing the EMI."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Defected ground structure with void having resistive material along perimeter to improve EMI suppression","description":"A multiple-layer circuit board has a signaling layer, an exterior layer, and a ground layer.
