A dual-band antenna designed for 5G communication based on a self-decoupled antenna

In this paper, a dual-band antenna for 5G communication based on an antenna design with self-decoupling properties is introduced.The antenna is composed of a self-decoupled antenna unit vertically placed on an 30×80 mm
²
ground plane and printed on 0.8 mm thick FR-4(εr = 4.4, tanδ = 0.02) substrate,and then added a pair of L-shaped coupling feeder structures on this basis.Simulation shows that the antenna has two operating frequency bands of 3.3-4.2GHz and 4.8-5GHz, and has good transmission and isolation in the above two operating frequency bands.Besides,it also has the advantages of small size, self-decoupling,high isolation,simple structure and easy processing.The antenna can be used as 5G mobile phone communication antenna unit.
