Performance Study of a 4-port UWB-MIMO/Diversity Antenna in Proximity to a Human Arm for WBAN Application

摘要

In this article, a parametric study of 4-port Ultrawideband (UWB) MIMO/diversity antenna near human Arm is presented. The S-parameters of MIMO is evaluated in free space and in proximity to human arm. To reduce simulation complexity and attain more accurate result layered flat and elliptical shape of a human arm model is used. Both the models embrace the important human tissue layers: skin, fat, muscle, and bone. The MIMO antenna parameter such as the peak gain, radiation efficiency, the envelop correlation coefficient (ECC) from the far field pattern for diversity performance has also been analyzed in the proximity of the human arm.
