Abstract :
In this article, a shorted helix antenna for an ingestible medical device applications is proposed. To investigate the performance of the antenna in an in-body environment, the antenna in the human-equivalent flat phantom is analyzed through simulation and measurement. The antenna is characteristic of wideband (386 ~ 409 MHz) covering MICS band. Radiation patterns have quasi-omnidirectional characteristic. In various organs, the antenna is characteristic not only of the return loss covering MICS band but also of quasi-omnidirectional radiation patterns.
