Abstract :
When the transmitter is held in the hand, the signal loss is larger than when it is attached to the wrist. When it is held in the hand, the coupling to the ground plane becomes strong because the palm is located on the coupling path to the ground plane. Therefore, much current near transmitter is distributed in the opposite direction of the receiver and less current flows to the receiver.
