摘要：

Multiple Input Multiple Output (MIMO) antennas have shown tremendous scope for increased capacity in wireless communication systems and are investigated for on-body networks in this work. A multi-antenna system based on truncated semi-elliptical patch antennas is presented and its characteristics evaluated. These patches are placed orthogonal to each other for good spatial and polarization diversity. Moreover, Artificial Magnetic Conductor (AMC) structures are used in the design to provide high isolation. The AMC-backed MIMO antenna provides 14.4% bandwidth and 10.6 dB isolation improvement, compared to the antenna without AMC. Besides, the channel capacity is also increased when AMC is integrated with the antenna. The diversity performance of the designed MIMO antenna is also evaluated in terms of envelope correlation coefficient and capacity loss for the lossy array. The proposed antenna offers spatial, polarization, pattern diversity, and good stability over the human body with improved channel capacity.
