Abstract

The invention discloses a dual-band eight-port MIMO terminal antenna based on radiator multiplexing technology, which includes a dielectric substrate and a pair of dielectric boards perpendicular to the dielectric substrate; a metal floor is arranged on the lower surface of the dielectric substrate, and a There are several antenna pair units on it, the antenna pair units include the first antenna unit on the inner wall of the dielectric board and the second antenna unit on the outer wall, each antenna pair unit includes two antenna ports, one antenna port is in the metal The first feed point on the floor; the other antenna port is the second feed point of the second antenna unit; the first antenna unit is connected to the first feed point feed through the feeder line and the coaxial inner core passing through the floor, The second antenna element is fed directly through the coaxial line. The antenna has the advantages of antenna-to-unit radiator multiplexing, no need for additional decoupling structures, dual-band operation and high isolation between antenna units, and is suitable for 5G smart terminals.

Description

technical field [0001] The invention relates to antenna design technology in the field of wireless communication, in particular to the design of a dual-band eight-port MIMO terminal antenna based on radiator multiplexing technology. Background technique [0002] MIMO (Multiple-Input Multiple-Output) technology is a technology that can make full use of space resources, realize multiple transmission and multiple reception through multiple antennas, and double the frequency without increasing spectrum resources and antenna transmission power. System channel capacity for wireless technologies. Since the MIMO technology has the advantages of multiplying the throughput, transmission distance and spectrum utilization rate of the communication system, the MIMO technology plays a very important role in the field of wireless communication. At present, handheld terminals are developing towards miniaturization and wearable, which makes the insufficient space for antenna design more ten...
