Problems solved by technology

Even so, the existing metamaterial small antennas are greatly restricted in the design process when faced with the problems of existing terminal equipment such as small size, low operating frequency, broadband multi-mode, etc.
[0003] At the same time, there are large differences in the working environment and electromagnetic characteristics of antennas in different products, which will lead to large differences in antenna performance in design and use, so the designed antenna must have strong adaptability and versatility
To sum up, the original technology will encounter problems of versatility and performance differences in use

Abstract

The invention relates to an antenna, which comprises a dielectric substrate and a metal sheet attached to a surface of the dielectric substrate. The metal sheet is surrounded by a feeder line, and the feeder line is fed in the metal sheet in a coupled manner; a first microgroove structure and a second microgroove structure which are asymmetric are arranged on the metal sheet, so that a metal cable is formed on the metal sheet; and the antenna is provided with space in advance, and electronic elements can be embedded in the space. The space embedded with the electronic elements is formed in the antenna, the properties of the antenna are finely adjusted by changing the properties of the embedded electronic elements, and the antenna which meets requirements on adaptability and generality. In addition, the invention also relates to a multiple-input and multiple-output (MIMO) antenna with a plurality of the antennas.

Description

Technical field [0001] The present invention belongs to the field of communications, and specifically relates to an antenna and a MIMO antenna with the antenna. Background technique [0002] In the traditional antenna design, when the antenna uses small space, low working frequency, and working in multi-mode, the performance of the antenna will be greatly restricted by the size of the antenna. The electrical length of the antenna corresponding to the reduction of the antenna volume will also be affected, and the antenna radiation efficiency and operating frequency will change. Traditional dipole antennas and PIFA antennas are incapable of facing the problems of small size and wide frequency bands of existing communication terminals, and the design is extremely difficult and ultimately cannot meet the requirements of use. Traditional antennas only use external matching circuits to achieve multi-mode radiation requirements in low-frequency design. After adding a matching network t...
