Abstract

The invention discloses a dual-frequency three-polarization MIMO antenna and a wireless communication device, the antenna includes a dielectric substrate, a floor, three feeder wires and two radiationpatches, the floor is arranged on the upper surface of the dielectric substrate, and a dumbbell-shaped gap is etched on the floor, the dumbbell-shaped gap has a long slit and two grooves connected toboth ends of the long slit, The three feeder lines and two radiation patches are arranged on the lower surface of the dielectric substrate, wherein one feeder line corresponds to the long slit of thedumbbell-shaped slot, and the other two feeder lines, two radiation patches and two grooves of the dumbbell-shaped slot are in one-to-one correspondence, each radiation patch is connected with a corresponding feeder line; The wireless communication device includes an antenna as described above. The antenna of the invention has dual-frequency and three polarization characteristics, and is easy toprocess, simple in structure, low in cost and wide in frequency bandwidth. The linear polarization can be applied to Bluetooth of 1.98 GHz to 2.9 GHz, Wi-MAX, ISM and other communication frequency bands, and circular polarization can be applied to the Wi-MAX of 3.13 GHz to 4.53 GHz, 5G and other communication bands.

Description

technical field [0001] The invention relates to a MIMO antenna, in particular to a dual-frequency triple-polarization MIMO antenna and wireless communication equipment, belonging to the technical field of wireless communication. Background technique [0002] Antenna is an important RF front-end device, and its performance requirements are getting higher and higher with the development of wireless communication technology. In order to meet the high-quality and high-data transmission requirements of the Internet of Things system, multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) technology has been well applied. Through multi-antenna technology and multi-output method, MIMO technology overcomes the multipath effect well, thereby improving the quality and communication capacity of the system communication, so it can meet the coverage of multiple mobile terminals. Because the application of MIMO antennas can greatly increase the transmission rate and channel...
