A kind of antenna and mimo antenna with the antenna

Abstract

The invention discloses an antenna; and the antenna comprises a first dielectric substrate and a second dielectric substrate, which are close to each other, wherein each of two opposite surfaces on the first dielectric substrate comprises a first metal sheet and a feeder line which is fed into the metal sheet; the surface of one side of the second dielectric substrate far away from the first dielectric substrate is provided with a third metal sheet; micro slot structures are formed in the two metal sheets on the first dielectric substrate in a hollow-out way; meanwhile, according to the invention, a space for an electronic element to embed is also formed in the antenna in advance. Through the adoption of the antenna disclosed by the invention, the metal sheets on the two surfaces of the first dielectric substrate and the third metal sheet on the second dielectric substrate can still satisfy requirements on antenna miniaturization and excellent performance when the antenna works at a lower working frequency section; meanwhile, through the adoption of the antenna disclosed by the invention, different electronic elements can be embedded, electromagnetic parameters of the antenna can be conveniently adjusted and the application range of the antenna is wider. In addition, the invention further provides an MIMO (Multiple Input Multiple Output) antenna with a plurality of the antennas, wherein the MIMO antenna obtains high isolation degree.

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] With the high development of semiconductor technology, higher and higher requirements are put forward for the integration of today's electronic systems, and the miniaturization of devices has become a technical issue of great concern to the entire industry. However, unlike the development of IC chips following "Moore's Law", radio frequency modules, another important component of electronic systems, face the difficult technical challenge of device miniaturization. The radio frequency module mainly includes main components such as frequency mixing, power amplifier, filter, radio frequency signal transmission, matching network and antenna. Among them, the antenna is the radiating unit and receiving device of the final radio frequency signal, and its working characteristics will directly affect the w...
