Abstract

The invention discloses an antenna device and an electronic device, which are used for solving the problem of limitation on the expansion effect of an antenna working frequency band by an adjustable capacitor in the prior art. The antenna device comprises an antenna, a frequency regulator and a control module, wherein the frequency regulator comprises a resonant module, a first end of the resonant module is connected with a signal transmission port of the antenna, the resonant module comprises an inductor and an adjustable capacitor, the inductor and the adjustable capacitor are connected in a first connection mode so as to expand the regulation range of the antenna working frequency band by the adjustable capacitor, and the control module is connected with the resonant module and used for regulating a capacitance value of the adjustable capacitor based on the target working frequency of the antenna so that the working frequency band of the antenna covers the target working frequency.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna device and electronic equipment. Background technique [0002] With the rapid development of mobile Internet technology, people have higher requirements for the portability of electronic devices, and the size of electronic devices is getting smaller and smaller. However, the antenna in electronic equipment has special requirements for the accommodation space. This is because the operating frequency of the antenna is related to the length of the antenna. The smaller the length of the antenna will make it difficult for the antenna to cover lower communication frequency bands, such as the commonly used in 4G communication. 700MHz frequency band. [0003] In the prior art, the resonant current of the antenna is changed through an adjustable capacitor, so as to widen the operating frequency band of the antenna. However, the adjustable range of the adjustable capacit...
