Abstract

The embodiment of the invention provides an antenna assembly and an electronic device, the antenna assembly comprises a first radio frequency port, a first matching port, a first switch and a second switch, the first radio frequency port comprises an input end and an output end, and the output end is connected with a radiator to receive and transmit a radio frequency signal; one end of the first switch and one end of the second switch are respectively connected with the input end of the first radio frequency port, the other end of the first switch is grounded, the first matching port is connected with the other end of the second switch, and the first matching port is connected with the tuning device. According to the antenna assembly provided by the embodiment of the invention, the resonance peak generated by the parasitic capacitance of the switch can be eliminated through the tuning device, so that the stray radiation index of the terminal antenna is reduced.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to an antenna assembly and electronic equipment. Background technique [0002] With the rapid development of communication technology, communication devices have become an indispensable tool in people's lives, and have brought great convenience to all aspects of users' lives. There are generally multiple antennas on communication equipment, especially in the future 5G equipment antenna frequency bands and the number will increase. [0003] When the mobile station is connected to a non-radiative pure resistive load or in the receiver state, the emission generated or amplified by the mobile station and radiated through the mobile station case, power supply, control equipment, and audio cables outside the operating frequency is called Radiation spurious (referred to as RSE). The causes of the spurious radiation problem include not only the excessive conduction ...
