Antenna design considerations for implantable devices in remote telehealth systems Take-Home Messages • Implantable sensors are pivotal to telehealth systems enabling continuous monitoring of a patient's vital health signs wirelessly. • Antennas are an integral element of these systems whose design is a complex task due to harsh and highly volatile in-body environment and requirements of robust and reliable performance while offering miniature structure, patient safety and biocompatibility. • A comprehensive critical review on the antenna design for implantable medical devices highlighting requirements, challenges, antenna types and human body effects on their performance shows that slotted patch antennas operating at higher frequencies can serve the purpose optimally. • The slotted patch antenna designed in the light of recommendations made offers a small size of 7.5×5×0.25 mm 3 with a-10 dB bandwidth of 25 MHz, a near-omnidirectional pattern and a gain of 1.7 dBi. • The paper can serve as a reference for the antenna designers working in the field of implantable devices providing state-of-the-art, current advancements, requirements, challenges as well as design rules.

This paper presents a design of high gain wideband antenna with metasurface for sub-6 GHz applications. The antennas at sub-6 GHz have a narrow bandwidth and low gain with a narrower axial ratio (AR). Hence, antennas combined with metamaterials are proposed to overcome these issues. The proposed metasurface antenna is designed with the implementation of W-shape transmission lines within the vias. The proposed antenna with metasurface is simulated using CST software and then fabricated on the FR4 substrate with (er=4.4 and h=1.6 mm). The antenna performance achieved a wide bandwidth of 85% and operates at 2 GHz to 5 GHz. A compact size of 45% is achieved with a high gain of 7.12 dB. The proposed antenna is suitable to be used in future sub-6 GHz applications.

“…Apart from virtual platforms, physical body phantoms which can be in liquid, semisolid (gel) or solid form have been developed for in-body communication studies [1]. Also, robust antenna designs are desired to improve radiation efficiency and prevent detuning in this environment [8][9][10]. For IB2IB communication, the dominant propagation mechanism is found to be a direct path between transmitting and receiving antennas.…”

Vertically-and horizontally-polarized antennas were investigated for on-body to on-body (OB2OB), in-body to in-body (IB2IB), and on-body to in-body (OB2IB) wireless propagations at frequencies of 915 MHz and 2.45 GHz. Theoretical formulations, simulations, and measurements were employed to study the effect of source antenna orientation on the attenuation of the radio frequency (RF) wave as it propagates around, inside, and through the body near the torso region. The results show that the vertical polarization is preferred for OB2OB communication, and the horizontal polarization is better for IB2IB communication. Furthermore, the dominant propagation mechanism and optimum antenna excitation for OB2IB communication are identified to be distance-dependent. The horizontallypolarized dipole is preferred at a shorter distance while the vertically-polarized dipole is preferred at a larger distance away from the source. The observed results were explained using the estimated attenuation rates of the different propagation mechanisms.
