    Abstract: A circuit board for reducing a transmission loss and a method for manufacturing the circuit board. In the circuit board including a ground layer and power layer facing each other, a wiring layer disposed between the ground layer and the power layer, and an insulating section formed between the ground layer and the power layer so as to sandwich the wiring layer therebetween, a low dielectric loss layer having a dielectric tangent lower than that of the insulating section is formed at least on an upper or lower surface of the wiring layer. According to such a circuit board, the low dielectric loss layer is formed on an interface between the insulating section and the wiring layer, and therefore, a transmission loss in a high frequency region is reduced.

    Abstract: The invention relates to a composite material and a high-frequency circuit substrate made from the composite material. The composite material includes: a thermosetting composition in an amount of 20 to 70 by weight with respect to the composite material, a fiberglass cloth processed by coupling agent; a powder filler; a fire retardant and a cure initiator. The thermosetting composition includes a resin with molecular weight thereof being less than 11,000, and a low-molecular-weight solid allyl resin. The resin is composed of carbon and hydrogen element. More than 60 percent of the resin is vinyl. The high-frequency circuit substrate made from the composite material comprises: a plurality of prepregs mutually overlapped and copper foils respectively covered on both sides of overlapped prepregs, wherein each prepreg is made from the composite material. The composite material of the present invention realizes easy manufacture of the prepreg and high bonding of the copper foil. The high-frequency circuit substrate made from the composite material has low dielectric constant, low dielectric loss tangent, and excellent heat resistance, and is convenient for process operation. Therefore, the composite material is suitable for making the circuit substrate.
