“…As for previous works, a helix implantable antenna working in 400 MHz is illustrated with a 4 MHz bandwidth . This narrow bandwidth (BW) is the weakness of the antenna as any condition that changes the resonant frequency makes the antenna useless.…”

As in medical applications dimensions reduction of implantable devices are of interest, periodic structures were used in substrate of the antenna to reduce the size of dual band miniaturized microstrip antennas even more. Designed substrate reduce the size to about 40%. The characteristics of miniaturized antenna with and without the periodic structure is compared and presented. © 2016 Wiley Periodicals, Inc.

“…For example, in [6], two antennas are proposed for an implantable medical device based on a PIFA configuration. In [7] a prototype of a complete PIFA antenna system including power supply and data communication, designed for an implanted glucose sensor, has been presented. A compact PIFA with bandwidth enhancement technique is proposed in [8] for implantable biotelemetry in MICS band.…”

This work deals with the optimization of an inverted F dual-band implantable antenna operating in Medical Device Radiocommunications Service (MedRadio, 401-406 MHz) and Industrial Scientific Medical (ISM, 902-928 MHz) applications bands. Artificial neural networks (ANNs) are implemented to minimize the size of the initial design. The ANN's output with the physical and dielectric parameters of antenna as inputs is tested using COMSOL Multiphysics. The obtained results regarding the return loss S 11 , resonant frequency and bandwidth of the antenna are presented and discussed. Indeed, the size of the antenna is reduced by 21.48% with respect to the initial size while preserving its initial good performance in both frequency bands.

“…Moreover, the antenna performance will be attenuated due to the effect of human body. There have been many reports on reducing the effect from human body [3,4,5], but their size still be larger for implants. In this paper, we proposed an implantable tag antenna which is designed to match the conjugate impedance of 9.3 − j55.2 Ω (μchip) [6] and its whole size is 15.75 mm × 4 mm.…”

In-body wireless communication has attracted increasing attention because it can not only be used in medical application but also be combined with wireless communication to replace the existing connectivity in biological telemetry monitoring [1]. Therefore, it is possible to integrate radio frequency identification (RFID) system into a brand-new device [2]. However, it has been very difficult to combine them due to high lossy of human body. In this paper, an implantable tag antenna which is designed to match an integrated circuit (IC) chip of 9.3 − j55.2 Ω [3] is proposed and realized in experiment. The dimensions of proposed antenna is 15.75 mm × 4 mm. The impedance characteristic of proposed antenna is analyzed by finite-difference timedomain (FDTD) method. By introducing the three-layered phantom, the measurements of impedance characteristic is implemented; moreover, the maximum read range of 1.3 cm is confirmed by a handy reader.
