Integrated Planar LTE MIMO Dual-antenna System on Laptop Computer's Hinge.

This paper presents an LTE MIMO dual antenna system for laptops. The LTE antenna is composed of a fed strip and a shorted strip. The antenna structure is very simple and can cover LTE octa-band operation (LET700/GSM850/900/GSM1800/1900/UMTS /LTE2300/2500) with the antenna size only 50 × 5 mm2 printed on the FR4 substrate. The LTE antenna is a design concept that integrates the metal hinges and ground plane into one of the antenna's resonant paths, which can effectively reduce the size of the antenna and can be tightly configured with the surrounding metal, while at the same time the antenna has good radiation characteristics. To effectively utilize the existing space of laptops, two LTE antennas of the same structure and size are symmetrically arranged in the clearance area on the left and right sides of the hinge of the laptop to form a MIMO dual antenna system. The measured isolation in the operating frequency band is better than 24 dB, while the measured antenna efficiency is better than 40%, which exhibits good antenna characteristics.
