ANTENNA SYSTEM, METHOD, AND WIRELESS COMMUNICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2023/169044

Kind Code:

A1

Abstract:

The present application relates to the technical field of terminals, and provides an antenna system, a method, and a wireless communication device. The system comprises a radio frequency chip, a controller, and a plurality of antennas; the radio frequency chip is connected to the plurality of antennas comprising a first antenna, a second antenna to an N-th antenna by means of a power amplifier and a switch; the first antenna is an antenna to be improved, and an i-th antenna is an auxiliary antenna, i being any one of 2-N; the controller determines that the working frequency band of the antenna of a wireless communication device is a preset frequency band to be improved of the first antenna; the preset frequency band to be improved comprises at least one frequency band; whether the i-th antenna works is determined; the i-th antenna does not work, the load state of a radio frequency input end of the i-th antenna is set, and the switch or Tuner state of the i-th antenna side is adjusted; the load state of the radio frequency input end is set to be one of the following: open circuit, isolation, or ground, and the i-th antenna becomes an auxiliary antenna. Thus, the performance of the first antenna is improved, for example, the bandwidth and efficiency are improved, or the SAR is reduced.
