Abstract

The invention discloses a ferrite-based MIMO (multiple input multiple output) terminal antenna comprising a rectangular dielectric slab, an earthing metal plate, the cuboid-shaped ferrite, a main antenna and a diversity antenna. The earthing metal plate is attached to one surface of the dielectric slab. The cuboid-shaped ferrite is attached to the other surface of the dielectric slab. The main antenna is attached to the ferrite. The diversity antenna is attached to the dielectric slab. The diversity antenna and the main antenna are arranged at opposite angle points of the dielectric slab. According to the arrangement, the ferrite is introduced and surrounded by the main antenna, due to high permeability and permittivity of the ferrite within 0.5GHz-3 GHz, size of the main antenna is narrowed greatly, expanded bandwidth is covered, and the miniaturization and multi-frequency problem of the conventional terminal antenna is solved; the diversity antenna is arranged at the opposite corner of the dielectric slab, high isolation of the MIMO antenna system is achieved with high application value.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a ferrite-based MIMO terminal antenna. Background technique [0002] The antenna can be regarded as a sensor that realizes the mutual conversion between radio frequency signals and electromagnetic waves. It is an important radio device for transmitting and receiving electromagnetic waves. Without an antenna, there is no wireless communication. [0003] In recent years, the mobile communication terminal equipment—the mobile phone has become the fastest-growing communication product in the world. Although the size of the current mobile phone is getting larger and larger, the space left for the antenna on the main board of the mobile phone is getting smaller and smaller. Therefore, with the increase of the working frequency band and the reduction of the size of the mobile phone antenna, the miniaturization and multi-frequency of mobile phone terminals will ...
