Title:
TUNING CIRCUIT AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/262478
Kind Code:
A1
Abstract:
The present disclosure provides a tuning circuit and a communication device. The tuning circuit comprises a tuning switch, a ground patch point, and at least two sets of patch units. Each set of patch units at least comprises a first patch point and a second patch point; the tuning switch comprises a standard port and at least one conversion port, and each set of patch units is connected to the corresponding conversion port; a first end of a first patch point and a first end of a second patch point in the same set of patch units are connected to the same conversion port; second ends of first patch points in different patch units are respectively connected to different contact points of an antenna; the second ends of all the second patch points are connected to the ground; and both ends of the ground patch point are respectively connected to the standard port and the ground. A closed port of the tuning switch is selected to switch the conduction of the contact points of the antenna or change the electrical properties of a ground feeder line of the antenna, thereby switching the electrical length of the antenna, and achieving the purpose of one switch for multiple purposes.
