Title:
ANTENNA ASSEMBLY, ELECTRONIC DEVICE, AND METHOD FOR IMPROVING RADIATION INDICATOR OF ANTENNA
Document Type and Number:
WIPO Patent Application WO/2019/149112
Kind Code:
A1
Abstract:
The present application provides a method for improving a radiation indicator of an antenna, applicable to an electronic device. The method comprises: coupling, by means of a coupler, an antenna signal amplified and output by an antenna amplifier, so as to obtain a coupling signal, and feeding back the coupling signal to a radio frequency transceiving unit; acquiring, according to the coupling signal, a non-linear harmonic signal generated by the antenna amplifier; generating an inverted pre-processing signal according to the non-linear harmonic signal; and sending the inverted pre-processing signal and the antenna signal to the antenna amplifier, so as to cancel out the non-linear harmonic signal generated by the antenna amplifier by means of the inverted pre-processing signal. The present application further provides an electronic apparatus and an antenna assembly adopting the method.
