Abstract

Embodiments of the present application provide an antenna assembly and an electronic device. The antenna assembly includes a first radio frequency port, a first matching port, a first switch, and a second switch. The first radio frequency port includes an input end and an output end, and the output end is connected to a radiator To send and receive radio frequency signals, one end of the first switch and the second switch are respectively connected to the input end of the first radio frequency port, the other end of the first switch is grounded, the first matching port is connected to the other end of the second switch, and the first matching port is connected to the ground. into the tuning device. The antenna assembly provided by the embodiment of the present application can eliminate the resonance peak caused by the parasitic capacitance of the switch through the tuning device, thereby reducing the stray radiation index of the terminal antenna.

Description

technical field [0001] The present application relates to the technical field of electronic devices, and in particular, to an antenna assembly and an electronic device. 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, the frequency and number of 5G equipment antennas will increase. [0003] When the mobile station is connected to a non-radiating purely resistive load or in the receiver state, the emissions generated or amplified by the mobile station outside the operating frequency radiated through the mobile station chassis, power supply, control equipment, audio cables are called It is radiation spurious (RSE for short). The causes of the problem of radiation spurs include not only the conduction spurs th...
