The invention provides an antenna tuning impedance control method, circuit, device and equipment, and a storage medium, and the method comprises the steps: receiving an address switching instruction through a first input end of a tuning switch module, and enabling the address switching instruction to be used for switching a target device address corresponding to the tuning switch module; a tuning control instruction is received from the serial bus according to the target device address through a second input end of the tuning switch module, and the second input end is connected with the serial bus; and controlling the grounding connection state of each impedance matching unit in the variable impedance module according to the tuning control instruction so as to adjust the impedance of the antenna, so that the signal receiving performance of the antenna can be kept within a preset range when the use state of the antenna in the target equipment to which the antenna belongs changes. By changing the device address of the tuning switch module, the technical problem of how to multiplex one set of antenna circuit to replace the switching function of multiple sets of antenna circuits is solved.
Description
technical field [0001] The present application relates to the field of wireless radio frequency circuits, and in particular to a control method, circuit, device, device and storage medium for antenna tuning impedance. Background technique [0002] With the vigorous development of smart wearable device technology, more and more wearable devices have begun to penetrate into every aspect of people's daily life, such as smart watches and health wristbands. For the development of wearable devices, the communication status or communication performance is a key factor affecting the user experience of the wearable device. Since the wearable device is in different use states, the human body will have different interferences on the communication performance of the antenna, which requires matching and adjustment of the impedance of the antenna. [0003] At present, in order to ensure the communication performance of the wearable device, the existing technology will equip the wearable ...
