Abstract

The present application provides an antenna assembly and an electronic device. The antenna assembly comprises a first radio frequency signal source, a first antenna radiator, a second antenna radiator, a first adjustment circuit, a second adjustment circuit, a mode switch and a controller, wherein the controller generates first, second and third control signals, the first radio frequency signal source generates a first radio frequency signal, the first adjustment circuit adjusts an equivalent electrical length of the first antenna radiator under the control of the first control signal to generate first electromagnetic wave signals of different bands, the second antenna radiator comprises a first portion arranged at a preset clearance away from the first antenna radiator, the first portioncouples the first electromagnetic wave signals to generate second electromagnetic wave signals, and when the mode switch is in a first state under the control of the second control signal, the secondadjustment circuit is electrically connected with the first portion, and the second adjustment circuit adjusts the equivalent electrical length of the first portion under the control of the third control signal to radiate the second electromagnetic wave signals.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to an antenna component and an electronic device. Background technique [0002] Antenna is a converter used to transform the guided wave transmitted on the transmission line into electromagnetic wave transmitted in the unbounded medium (usually free space), or convert the electromagnetic wave transmitted in the unbounded medium into the electromagnetic wave that can be transmitted on the transmission line A device for guided waves. An electronic device such as a mobile phone usually includes an antenna to realize the communication function of the electronic device such as the mobile phone. However, in existing electronic devices, when the antenna receives the radio frequency signal (guided wave) from the excitation source and converts it into an electromagnetic wave signal (electromagnetic wave) according to the radio frequency signal, the frequency band that can be re...
