Abstract	The RF transmission between two human bodies was characterized and a channel model developed for UWB communications. From this study, it was found that the path loss is greatly dependent on the position of the transmit and receive antennas on the body as well as the relative orientation of the human bodies. The change in the radiation patterns of the antennas due to the presence of the human body affects the path loss. As compared to the free space path loss, the path loss when the antennas were mounted on the body can be reduced for certain body orientations. The chest-to-chest configuration generally demonstrates a lower path loss and a higher path loss exponent compared to the chest-waist and waist-to-waist configurations. The improvement in the path loss is the most significant for the waist-waist configuration due when the antennas are mounted 5 mm away from the human body due to the reduced blockage by the arm. Also, the path loss is greater when the upper UWB band is considered as compared to the lower and entire UWB bands.
