Abstract :
This paper characterizes and analyses the link budget requirements for the conformal capsule antenna in the medical capsule imager system. A link budget is developed for the capsule system based on certain parameters (frequency, SAR, power limitations) and it is shown that using the present antenna system; a reliable communication link can be developed for indoor communication for bio-telemetry applications. The polarization diversity exhibited by the conformal capsule antenna is tested and compared to simple dipole design. Due to diverse polarization, a reliable link is obtained irrespective of the capsule location and orientation and this study is discussed in detail.
