Abstract

The invention discloses an antenna device and a mobile terminal. The antenna device comprises a conductor, a feed source, a resonance circuit and a low-frequency inductor. The slot is provided with a slot. The conductor is separated into a first radiation part and a second radiation part which is isolated from the first radiation part, and a connecting part which is electrically connected between the first radiation part and the second radiation part by the slot. The feed source is electrically connected with the first radiation part and feeds a feed signal to the first radiation part. The resonance circuit is electrically connected with the first radiation part and the second radiation part and used for enabling the conductor to radiate high-frequency resonant frequency. The low-frequency inductor is electrically connected with the conductor and used for enabling the conductor to radiate low-frequency resonant frequency. According to the antenna device, the high-frequency resonant frequency and the low-frequency resonant frequency can be generated and coexist.

Description

technical field [0001] The present invention relates to the field of antenna technology, and in particular, to an antenna device and a mobile terminal. Background technique [0002] As the application of smart phones becomes more and more extensive, the requirements for high-frequency or low-frequency frequencies of antennas in mobile phones are becoming more and more strict. The antenna of a conventional mobile phone uses a switch to ground one end and connect the other end to the radiator, and is opened or closed by the switch, so that the antenna radiates the high-frequency resonance frequency or the low-frequency resonance frequency, so as to meet the bandwidth requirements of the antenna. However, in this way, the antenna can only radiate the frequency of the high-frequency resonance or the frequency of the low-frequency resonance, and cannot make the high-frequency resonance frequency and the low-frequency resonance frequency coexist.
