A MIMO Antenna System using Wireless Terminals for Improving of Envelop Correlation Coefficient

摘要

According to another aspect of the present invention, there is provided a MIMO antenna system for a wireless terminal for improving ECC, comprising: a grounding unit for grounding an antenna on a main PCB substrate; A first antenna unit positioned at a lower end of the ground unit; A second antenna unit located at a right end of the ground unit; And a phase adjustment circuit connected to the first antenna unit or an extended transmission line connected to the second antenna unit. Accordingly, it is an object of the present invention to provide a method and apparatus for generating a phase shift between multiple antenna elements by using an Adjusted Phase Matching Circuit and an Extensive Transmission Line for improving ECC, The present invention provides a MIMO antenna system for a wireless terminal having stabilization of a MIMO antenna system by effectively minimizing an amplitude of an MIMO antenna system and ensuring good characteristics of an ECC in a low frequency band where characteristics can not be secured, It is effective.
