Abstract
A highfrequency package has an excellent high-frequency characteristic in a band from quasi-millimeter wavelength to 90 GHz frequency. A sealed construction can be easily manufactured, leading to a reduction in cost, and is excellent in strength. A ring-shaped frame and signal lines facing each other with the ring-shaped frame between in the inside and outside regions separated by the ring-shaped frame are formed on one main surface side of a dielectric substrate, and grounds are formed around the signal lines with gaps interposed between in the same plane, while signal lines and a ground around the signal lines with gaps interposed between in the same plane are formed on the other main surface side of the dielectric substrate, wherein conductive vias for vertically connecting each of one end portions of the signal lines and both end portions of the signal line are formed, and a plurality of conductive vias for vertically connecting the grounds and the ground are formed at prescribed intervals on both sides with the signal lines between.
