Title:
WIRELESS ANTENNA AND TOUCH SENSOR TOUCHPAD MULTIPLEXING STRUCTURE AND WIRELESS WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/142969
Kind Code:
A1
Abstract:
A wireless antenna and touch sensor touchpad multiplexing structure and a wireless wearable device. The wireless antenna and touch sensor touchpad multiplexing structure comprises a radiant touchpad, a first electric conductor, a first circuit, a second circuit, and a frequency dividing circuit. The radiant touchpad is configured to transmit and receive a radio frequency signal and receive a touch signal. The first electric conductor is electrically connected to the radiant touchpad. The first circuit is electrically connected to the radiant touchpad by means of the first electric conductor. The frequency dividing circuit is electrically connected to the second circuit and the first electric conductor separately, and is located between the second circuit and the first electric conductor. The wireless antenna and touch sensor touchpad multiplexing structure can implement the separation of the touch signal and the radio frequency signal, and can solve the problem of mutual interference caused by the space limitation of the wireless wearable device.
