Problems solved by technology

Traditional antenna devices achieve multi-band by increasing the size of the antenna or adding multiple parasitic resonances, or using duplexers, combiners and other devices to separate the ports of the antenna device. This method will increase the space size of the antenna device and thus It is not conducive to the use in wireless communication devices that are increasingly miniaturized, and increases the loss on the transmission path, making the signal transmission efficiency low

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] An antenna device can be used in the wireless communication process in the wireless communication equipment. The antenna device includes an antenna ground, a feeding end, a sharing unit, a first radiating unit, a second radiating unit and a band stop unit. Wherein, the common unit is respectively connected with the feeding end, the first radiation unit and the second radiation unit. The first radiating unit and the sharing unit form a first antenna, and the resonant frequency of the first antenna is the first resonant frequency. The second radiating unit and the sharing unit form a second ...

Abstract

The invention relates to an antenna device comprising an antenna ground and a feed-in end. The antenna device further comprises a common unit which is connected with the feed-in end, a first radiation unit which is connected to the common unit and forms a first antenna together with the common unit, a second radiation unit which is connected to the common unit and forms a second antenna together with the common unit, and a band-stop unit which is connected between the second radiation unit and the antenna ground, wherein the path length of the second radiation unit is greater than the path length of the first radiation unit, the band-stop unit is in a high-impedance state when the working frequency is the resonance frequency of the second antenna, the band-stop unit is in a switched-on state when the working frequency is greater than the resonance frequency of the second antenna, and the band-stop unit forms a third antenna together with the common unit, the second radiation unit and the antenna ground. A multiband antenna device can be achieved on the premise of not increasing the space size of the antenna device. The invention further relates to a piece of wireless communication equipment.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless communication device and an antenna device thereof. Background technique [0002] Since different wireless communication providers use different signal transmission frequency bands, to ensure that wireless communication equipment can receive wireless signals conveniently and clearly, its antenna device needs to be able to work in multiple frequency bands. Traditional antenna devices achieve multi-band by increasing the size of the antenna or adding multiple parasitic resonances, or using duplexers, combiners and other devices to separate the ports of the antenna device. This method will increase the space size of the antenna device and thus It is unfavorable to be used in wireless communication devices that are increasingly miniaturized, and increases the loss on the transmission path, making the signal transmission efficiency low.
