Design of Multiple Input Multiple Output (MIMO) Antenna for Compact Wearable Applications

The MIMO (Multiple Input Multiple Output) is one of the technology of an antenna which is mainly applied for the purpose of wireless communications and in biomedical applications. Here, the condensed novel substrate antenna is used based on the five elements which has presented in this paper. Then the two tuned elements are bended which provides drifted antenna consists of carrying the high term development bands or lines of frequency down at 1.5GHz (786-825 MHz). Based on the correlation coefficient the MIMO antenna is designed among the expected value of 0.5. The damage of the human skin or flesh outcomes the droplets of the antenna gain expansions to 1.5dBi and 1.3dBi correspondingly, for the required two antennas. Here, the antenna is simulated in CST software on the substrate of FR-4 and the dimension of fabrication is 75 mm *150 mm *2.55 mm. Hence, it is most inexpensive for a wearable uses owing to its compressed size, one layer arrangement, informal combination, forcefulness, and sensible gain of on-body antenna structure.
