Title:
TRANSMISSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/162654
Kind Code:
A1
Abstract:
This transmission circuit includes: a plurality of impedance circuits that each have a different impedance; a plurality of switching elements that are each connected to one of the plurality of impedance circuits; and a control circuit that is configured so as to control the opening and closing of the plurality of switching elements. The control circuit is configured to be able to perform control so as to selectively change the opening and closing of the plurality of switching elements, and rotate a reflection coefficient of an antenna-side output terminal in a complex plane, along a circle that is warped in comparison to a perfect circle.
