TRANSMISSION CIRCUIT
This abstract first appeared for US patent application 18838608 titled 'TRANSMISSION CIRCUIT
Original Abstract Submitted
A transmission circuit includes a plurality of impedance circuits having an impedance different from each other, a plurality of switch elements, each of which is connected to a corresponding one of the plurality of impedance circuits, and a control circuit configured to control opening and closing of the plurality of switch elements. The control circuit can control, by selectively changing the opening and closing of the plurality of switch elements, a reflection coefficient of an output terminal on an antenna side to rotate in a complex plane and on a circle that is distorted in comparison to a perfect circle.
