Abstract
Abstract A multilayer flexible circuit is provided with integral capacitors. These capacitors are in the form of rigid dielectric elements embedded within the flexible circuit at appropriate locations between two circuit patterns. The circuit pattern may include inductors which cooperate with the capacitors to provide filtering.
