Title:
ANTENNA ASSEMBLY AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/179825
Kind Code:
A1
Abstract:
An antenna assembly, which comprises: a conductive frame (110), provided with at least one slot (111), the slot (111) at least dividing the conductive frame (110) into a first conductive branch (113) and a second conductive branch (115) that are independent, wherein a feed point (S1) is provided on the first conductive branch (113), and a connection point (S2) is provided on the second conductive branch (115); a resonant circuit (210), a signal source (220) coupling a feed current signal to the first conductive branch (113) by means of the resonant circuit (210) and the feed point (S1), wherein the current signal is coupled to the second conductive branch (115) by means of the slot (111); generating a plurality of resonant frequencies on the first conductive branch (113) and the second conductive branch (115) under the resonant regulation by the resonant circuit (210); a switching circuit (230) used for performing switching regulation on the current signal on the second conductive branch (115), such that a radio frequency signal having a plurality of working bands is simultaneously radiated on the first conductive branch (113) and the second conductive branch (115), wherein at least two working bands are switchable.
