Characteristic current based MIMO antenna performance estimation in chassis mode platform

Characteristic mode theory (CMT) is an effective method for designing MIMO system. Establishing reliable channel is an important issue in communication systems. And MIMO system based on CMT is one strong candidate among the other approaches. In this paper, some design examples of MIMO antenna on chassis and its coupler structure is shown. The proposed coupler is useful to excite a desired mode from the other chassis modes. The estimation is conducted with Envelope Correlation Coefficient (ECC). The simulation results are also demonstrated.
