Abstract
In this paper, design of a UWB MIMO antenna for an on-body application is proposed and antenna performance with body effect and the impact on the human body are investigated. The proposed MIMO antenna is composed of UWB antenna above ground plane and an additional plunger shaped isolator located between the two monopole antennas to enhance the isolation characteristic. The simulation and measurement are performed to analyze the effect of the human body on antenna performance when the human body is located in the near field of the antenna. According to the measurement results, the measured SAR values for antennas 1 and 2 are 0.132 W/kg and 0.08 W/kg, respectively when 0.5 mW input power is delivered. These values satisfy the FCC guideline which ragulates that the 1-g average SAR should be lower than 1.6 W/kg.
