Abstract :
In this paper, we present a discussion of work done in tracking an embedded object. A special application to telemetry capsules in the gastrointestinal (GI) tract using radio frequency (RF) signals is highlighted. We present the mathematical analysis of the procedure and consequently, an experimental validation of the concept from data captures to position determination using non linear least squares approximation. Finite difference time domain (FDTD) simulation of a suitable dipole antenna employed in the work is also presented to show that within the test range, the radiation pattern of a dipole at about 433 MHz is suitable for detecting an embedded object that is subject to the characteristics of tissue and other related structures.
