In this paper, Theory of Characteristic Mode (TCM) has been exploited to enhance the performance of MIMO antenna. Characteristic modes of Chassis has been analyzed, it has been observed that only one mode is resonating around 1GHz. To enable more than one characteristic mode to resonate around 1GHz, Two metal strips are attached along the length of the chassis with the help of shorting pins. A new characteristic mode has been enabled at about 900 MHz due to this modification. In order to obtain characteristic mode at further lower frequency, the newly attached metal strip is meandered. A shift in the characteristic mode has been observed due to this. Afterwards, Dual antenna design is proposed. The Dual antenna consists of metal strip antenna and coupled antenna. The feeding method is proposed with the help of theory of characteristic mode (TCM) to excite the antenna chassis mode and metal strip mode efficiently. The results shows that the strip antenna covers 849-953MHz (LTE Band8) and chassis mode antenna covers frequency 950-1120 MHz. © 2017 IEEE.
