Omnidirectional indoor distribution MIMO antenna

Abstract

The embodiment of the invention provides an omnidirectional indoor distribution MIMO antenna. The omnidirectional indoor distribution MIMO antenna comprises a vertical polarization antenna unit and ahorizontal polarization antenna unit, the vertically polarized antenna unit comprises three centrosymmetric and vertically arranged radiation patches, a circular coupling patch and a coupling ring, the circular coupling patch is arranged at the top ends of the three radiation patches, the coupling ring is fixed on the floor, bottoms of the three radiation patches are located in the coupling ring and fixed on the floor; the horizontally polarized antenna unit comprises a plurality of groups of dipoles which are arranged in a central symmetry mode and printing power dividers which are arranged corresponding to the dipoles respectively, the dipoles are printed on a first plate face of the annular medium, the printing power dividers are printed on a second plate face, opposite to the first plate face, of the annular medium, and the annular medium is vertically fixed on the circular coupling patch through a plurality of bolts. According to the omnidirectional indoor distribution MIMO antenna, the height of the existing indoor distribution MIMO antenna is reduced, and the antenna has good omnidirectional radiation performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an omnidirectional room division MIMO antenna. Background technique [0002] The indoor distribution system plays an extremely important role in the mobile communication network. In order to further improve the performance of the indoor distribution network, Multiple-Input Multiple-Output (MIMO) technology plays an important role. MIMO technology requires the use of multi-antenna technology at both the transmitting and receiving ends of the system, the use of multiple antennas or antennas with multiple polarization modes for signal transmission and reception, and the use of space resources and multipath of wireless channels to establish parallel The transmission channel realizes the communication mode of multi-receiving and multi-sending. MIMO technology can greatly increase channel capacity, improve spectrum utilization, eliminate polarization mismatch, increase ...
