Abstract

The invention discloses a double-loop antenna, an antenna module and a mobile terminal. The antenna comprises a first antenna radiation unit and a second antenna radiation unit, wherein the first antenna radiation unit and the second antenna radiation unit are arranged on different planes in a staggered manner but are not connected, the first antenna radiation unit is provided with a first tail end and a second tail end, the second antenna radiation unit is provided with a third tail end and a fourth tail end, during use, any one of the first tail end, the second tail end, the third tail end and the fourth tail end serves as a feed part to be connected with a signal source, and the other tail ends serve as grounding parts to be connected with metal ground. The antenna is advantaged in thatthe first antenna radiation unit and the second antenna radiation unit are designed to be arranged on different planes in a staggered manner but not connected, the antenna can meet the requirements of different communication systems for frequency bands, the frequency band coverage range is wider, the space effective utilization rate is higher, and due to the fact that the signal source can be connected with any tail end, the layout design is flexible, and the antenna is suitable for large-range application and popularization.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of antenna multi-frequency design, and in particular to a double-loop antenna, an antenna module and a mobile terminal. Background technique [0002] With the rapid development of wireless communication technology, people have more and more urgent needs to obtain information anytime and anywhere wirelessly, and microwave / radio frequency circuits and systems have received more and more attention. As an important part of the microwave radio frequency circuit, the antenna plays the role of signal radiation and reception. [0003] In order to adapt to the multi-function, high data transmission rate and miniaturization of the current mobile terminal, the antenna is required to have the characteristics of multi-band, compact structure and low cost. However, the result of miniaturization is that the space in the mobile terminal is gradually compressed, which makes the multi-frequency design o...
