Abstract
Impulse Radio-Ultra-Wideband (IR-UWB) is gaining popularity for a variety of short-range Wireless Body Area Network (WBAN) applications. In-body to outside-body communication is one of the possible applications of IR-UWB signals. This paper analyses various aspects related to implant communication of IR-UWB signals, antenna gain characteristics, propagation loss, and Bit Error Rate (BER) variation. The development of an implantable IR-UWB antenna that operates in the frequency range of 3.5-4.5 GHz is discussed. Its operation within the implant environment is described in terms of simulated and measured antenna gain. Experiments that evaluate the path loss and BER characteristics of IR-UWB communication are carried out using pork, which is used as the human tissue simulating material. Experimental results show a path loss variation of more than 90 dB for an in-body propagation distance of 100 mm. The BER experiments show that this IR-UWB system can operate at a BER of 10-3 for an in-body propagation distance of 100mm when it is operating at a data rate of 1Mbps.
