    Abstract: A hybrid electromagnetic bandgap (EBG) structure for broadband suppression of noise on printed wiring boards includes an array of coplanar patches interconnected into a grid by series inductances, and a corresponding array of shunt LC networks connecting the coplanar patches to a second conductive plane. This combination of series inductances and shunt resonant vias lowers the cutoff frequency for the fundamental stopband. The series inductances and shunt capacitances may be implemented using surface mount component technology, or printed traces. Patches may also be interconnected by coplanar coupled transmission lines. The even and odd mode impedances of the coupled lines may be increased by forming slots in the second conductive plane disposed opposite to the transmission line, lowering the cutoff frequency and increasing the bandwidth of the fundamental stopband. Coplanar EBG structures may be integrated into power distribution networks of printed wiring boards for broadband suppression of electromagnetic noise.

    Abstract: Magnetic field distribution and mutual capacitance control for transmission lines are provided. A first circuit board is fabricated by attaching a reference plane layer to a dielectric material layer, and attaching a first trace to the second surface of the dielectric material. A surface profile of the reference plane layer is modified to decrease a resistance of a return current signal path through the reference plane layer, to reduce a magnetic field coupling between the first trace and a second trace. A second circuit board is fabricated by attaching a reference plane layer to a dielectric material layer, attaching a trace to the dielectric material, and forming a solder mask layer on the dielectric material layer over the trace. An effective dielectric constant of the solder mask layer is modified to reduce or increase a mutual capacitance between the first trace and a second trace on the dielectric material.

    Abstract: A mounting region is provided at an approximately center of one surface of an insulating layer. A conductive trace is formed so as to outwardly extend from inside of the mounting region. A cover insulating layer is formed in a periphery of the mounting region so as to cover the conductive trace. A terminal of the conductive trace is arranged in the mounting region, and a bump of an electronic component is bonded to the terminal. A metal layer made of copper, for example, is provided on the other surface of the insulating layer. A pair of slits is formed in the metal layer such that a region being opposite to the electronic component is sandwiched therebetween. Each slit is formed so as not to divide the metal layer into a plurality of regions.
