Abstract

The invention discloses an antenna device. When the antenna device is arranged in an electronic device comprising a circuit board, the antenna device is used for receiving and transmitting wireless signals of the electronic device. The antenna device comprises a radiating body and an electric array susceptance component, wherein the radiating body comprises a first end which is grounded due to arrangement on the circuit board, the electric array susceptance component has a second end and a third end, the second end is connected with the radiating body, the third end is grounded due to arrangement on the circuit board, the electric array susceptance component has K kinds of different impedance values, and K is an integer greater than or equal to 2; when in a powered-on state, the radiating body can generate K kinds of resonance oscillation signals different in frequency range based on the K kinds of different impedance values.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an antenna device and electronic equipment. Background technique [0002] With the continuous development of the WLAN technology in the wireless communication technology, more and more electronic devices, such as mobile phones and tablet computers, have a wireless Internet access function. In order to realize the wireless Internet access function, it is necessary to install an antenna in the electronic device. At the same time, the continuous advancement of communication technology has made more and more requirements for communication frequency bands, such as covering 2G / 3G / 4G, especially the frequency band span of LTE4G from low frequency 704MHz to high frequency 2690MHz. Consumers' demand for small wireless devices increases the difficulty of antenna design. The compromise method is to divide the antenna frequency bands for different regions, which leads to a large amount o...
