Design of an antenna for an ingestible capsule endoscope system

Abstract

In this paper, an antenna used in an ingestible capsule endoscope system is proposed. To achieve miniaturization and a wide bandwidth, an inverted-F antenna with a meandered strip line was used. The antenna performance in a human voxel model is analyzed through simulation. In order to investigate the performance of the proposed antenna in an indoor environment, a typical sickroom model is setup, and the propagation characteristics between the proposed antenna and the base station are analyzed at 1.4 GHz. The per~ormance of the fabricated antenna is verified by companng the measured data with that of the simulation when the antenna is placed in a human-equivalent liquid phantom.

Examination of Impedance Response of Capsule- Integrated Antennas Through Gastrointestinal Tract

“…Hence, the ingestible antenna must be designed meticulously so that it is able to meet the requirements of the wireless link in terms of power and efficiency. Various types of antenna designs have been proposed in the literature for ingestible systems such as helix antenna [4], microstrip antenna [5], coil antenna [6], and inverted-F antenna [7].…”
