In this paper, a multi-band antenna based on a single ring slot is proposed for 5G smartphone applications. The proposed antenna consisting of a full metal frame and a ring slot operates at three frequency bands of 5G communications in China which are 2.515-2.675 GHz, 3.4-3.6 GHz and 4.8-4.9 GHz. By inserting grounded stubs, the antenna at three frequency bands is constructed. The advantages of the proposed antenna include multi-band operation, high isolation and compact structure.
