Abstract
A signal process apparatus of the present invention is capable of shifting phases of signals inputted thereto and attenuating the signals, simultaneously. The signal process apparatus includes a dielectric member provided with a first and a second portions, a plurality of transmission lines positioned opposite the dielectric member for transmitting the signals and means for rotating the dielectric member to an axis perpendicular to a surface of the dielectric member which is parallel to the transmission lines. In the signal process apparatus, a dielectric constant of the first portion is different from that of the second portion. Each of the signals is inputted to a corresponding transmission line. After each of the signals is passing through the corresponding transmission line, it has a phase shifted by rotating the dielectric member.
