Document Type and Number:
Japanese Patent JP7420217
Kind Code:
B2
Abstract:
A distributing/synthesizing circuit includes first to fourth ports. A first radio frequency circuit transmits and receives a radio frequency signal to and from the first port through a first transmission line. A second transmission line is connected to the second port. A first radiating element is connected to the third port and the fourth port through a third transmission line and a fourth transmission line, respectively. The distributing/synthesizing circuit distributes and outputs the radio frequency signal input to the first port to the third port and the fourth port, synthesizes radio frequency signals that are reflected by the first radiating element and that are input to the third port and the fourth port to output the synthesized radio frequency signal to the second port. The second transmission line is longer than all of the first transmission line, the third transmission line, and the fourth transmission line.
