Abstract

The invention discloses a low-profile full-waveband WLAN-MIMO indoor distributed antenna with an orthogonal or circumferential distribution radiation body. The antenna is composed of a transverse dielectric plate, a longitudinal dielectric plate, a reflecting plate, a Balun, back strips and a vibrator, wherein the back strips and the vibrator are manufactured by adopting the copper coating technology. The antenna is in the form of a MIMO antenna capable of covering the full WLAN frequency band. According to the technical scheme of the invention, the relative positions of the back strips relative to the vibrator are changed. Meanwhile, the back strips are coupled to the vibrator to generate the inductive capacitance so as to adjust the performances of an ultra-wideband antenna, such as working waveband, antenna gain, antenna directionality and the like. Through adjusting the distance and the angle between antenna units, the antenna is minimized, high in isolation degree, low in correlation coefficient and high in gain. The antenna covers all wide frequency bands during the current wireless communication process and is large in data capacity.

Description

technical field [0001] The present invention relates to a MIMO antenna suitable for indoor use, more particularly, to a low-profile full-band WLAN-MIMO indoor distributed antenna with an orthogonally distributed radiation body or a circumferentially distributed radiation body. Background technique [0002] In order to improve the throughput, transmission distance and reliability of WLAN (Wireless Local Area Network), the new generation of wireless local area network standard 802.11n introduces MIMO (Multiple-Input Multiple-Out) technology, and WLAN MIMO system The realization of MIMO not only depends on the design of the MIMO radio frequency module, but also depends on the development of the base station MIMO antenna responsible for the upload and download functions. Its performance directly affects the overall performance of the entire WLAN MIMO system. Therefore, the popularization and application of WLAN MIMO system puts forward two basic requirements for the development ...
