Abstract

The invention relates to a multiband antenna and a mobile terminal. The multiband antenna comprises a substrate as well as a radiation patch, a first resonator and a grounded metal patch which are arranged on the substrate, the radiation patch is used for radiating an antenna signal; the first resonator possesses a composite left-and-right-hand structure and is connected with the radiation patch,the first resonator is configured to receive a fed-in antenna signal and realize more than one resonant modes under excitation of the antenna signal; and the grounded metal patch is arranged at one side of the first resonator at an interval, is connected with the first resonator by virtue of a microstrip structure and is used for providing a ground loop for the first resonator. Accordingly, the invention provides a mobile terminal containing the multiband antenna. The multiband antenna provided by the invention meets design requirements of the multiband antenna, operation bandwidth is increased, and design cost and design space are effectively reduced.

Description

technical field

[0001] The invention relates to the technical field of antennas, in particular to a multi-band antenna and a mobile terminal. Background technique

[0002] At present, smart mobile devices, such as smart phones, personal device assistants PDA, tablet computers and other portable mobile terminals have become more and more popular. For mobile terminals, the design of the antenna will determine the reliability and efficiency of wireless signal transmission, so the antenna's Design is one of the cores of mobile terminals. With the popularization of the Long Term Evolution (LTE) and the arrival of the fifth generation wireless communication technology (The Fifth Generation Mobile Systems, 5G for short), multi-band and high-bandwidth are the core demands of antenna design. For example, in the field of 5G communication, in addition to covering the existing LTE frequency band, its 5G antenna working frequency band has also increased the working frequency band below ...
