A Dual-band Repeater Antenna for On-Body Receiver Unit of Wireless Capsule Endoscope

Research output: Chapter in Book/Report/Conference proceedingConference contributionScientificpeer-review

Abstract

A dual-band repeater antenna for the on-body receiver unit of a wireless capsule endoscope system is proposed at the Medical Device Radiocommunications (MedRadio, 401-406MHz) band and at the Industrial, Scientific, and Medical (ISM, 2. 4-2.48GHz) frequency band. The radio link from the capsule transmitter to the on-body receiver utilizes the MedRadio band, whereas the on-body to off-body communication happens at the ISM band. The design is evolved from a classical printed monopole/dipole structure. It utilizes two rectangular offset patches, printed on two sides of a substrate. Both the top and bottom patches are configured in such a way that wideband matching with sufficient radiation efficiency is achieved at both bands. A multi-layer canonical tissue phantom and realistic human body model were used for the numerical studies. The latter was validated through ex-vivo measurements on a real human body. The measured -10dB impedance matching bandwidths are 44% and 14.4% at the MedRadio and ISM band, respectively show a good agreement with the simulated one.
