Document Type and Number:
Japanese Patent JP6867322
Kind Code:
B2
Abstract:
A circuit includes a first input and output unit to which a current, a voltage, or an electromagnetic wave (referred to as "current or the like" below) is applied, a second input and output unit to which the current or the like is applied, a first board including a matrix circuit which is formed by a first line and includes a 90-degree hybrid circuit and a delay line, the first line in which one end is connected to the first input and output unit and a tip of the other end is opened, a second board including a second line in which one end is connected to the second input and output unit, and a tip of the other end is opened, and a shielding plate including an opening portion. The shielding plate causes the current or the like directed from one end of the first line, which has the opened tip, toward the shielding plate to propagate to one end of the second line, which has the opened tip, through the opening portion. In addition, the shielding plate causes the current or the like directed from the one end of the second line, which has the opened tip, toward the shielding plate to propagate to the one end of the first line, which has the opened tip, through the opening portion.
