Title:
ANTENNA MATCHING CIRCUIT, FREQUENCY BAND SELECTION METHOD, AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/068610
Kind Code:
A1
Abstract:
Disclosed in the present invention are an antenna matching circuit, a frequency band selection method, and an apparatus. The antenna matching circuit comprises an antenna, a first frequency band matching circuit, a second frequency band matching circuit, a frequency band selection switch, and a radio frequency integrated circuit. The antenna is connected to one end of the first frequency band matching circuit, and is also connected to one end of the second frequency band matching circuit. One end of the frequency band selection switch is connected to the other end of the first frequency band matching circuit and is also connected to the other end of the second frequency band matching circuit, and the other end of the frequency band selection switch is connected to one end of the radio frequency integrated circuit. In the present invention, a frequency band selection switch is arranged, and different triggering signals trigger the frequency band selection switch to be switched to different matching circuits; the following problems are resolved: only an antenna switch module can be used to select which frequency band can be used, and some frequency bands fail to be accurately selected because the isolation of the antenna module components is insufficient.
