Abstract

The invention relates to an antenna which comprises a first dielectric substrate and a second dielectric substrate. Metal sheets are arranged on two surfaces of the dielectric substrates, space area of the antenna is used fully, and the antenna can be operated at low operating frequency under the environment and simultaneously meets requirements for miniaturization, low operating frequency and broadband multi-mode. In addition, a multiple input multiple output (MIMO) antenna with a plurality of the antennas is further related. The MIMO antenna has high isolation.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an antenna and a MIMO antenna with the antenna. Background technique [0002] In traditional antenna design, when problems such as small antenna space, low operating frequency, and multi-mode operation are encountered, 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 volume of the antenna will also be affected, and the radiation efficiency and operating frequency of the antenna will change. Traditional dipole antennas and PIFA antennas are powerless when faced with the problems of small size and broadband in existing communication terminals, and the design is extremely difficult and ultimately cannot meet the requirements of use. In the design of traditional antennas in the low frequency band, only external matching lines are used to meet the multi-mode radiation ...
