“…Since size and shape of the human tissue were found to have small influence on the antenna resonance [3], instead of relying on a detailed body model, simulation time is decreased by simply positioning the antenna on a small homogeneous block (length and width 80 mm, height 20 mm) with dielectric properties corresponding to the MSL2450 fluid. This approach is validated in the next subsection by means of measurements.…”

“…Wireless medical devices can be implanted almost everywhere in the human body, providing remote monitoring of patients by transmitting the collected biometric data to a receive station, which can help to temper the rising medical cost brought on by aging of the population. Such implantable antennas operate in the 402-405MHz Medical Implant Communication Services (MICS) band [3], the 2.45GHz Industrial, Scientific and Medical (ISM) band [4] or in multiple bands [5].…”

Abstract-Long-range in-body biomedical telemetry enables monitoring of physiological parameters while maintaining mobility and freedom of movement. This emerging technology creates new applications in medicine, clinical research, wellness, and defense. Current in-body biotelemetry devices operate within about a meter around a user that limits their applicability. Here we examine the variety of approaches that, combined, can significantly extend the operating range. The radiation efficiency is constrained by attenuation and reflection losses in tissues. First, choosing an optimal operating frequency can minimize the losses. A specific antenna design is then required to decouple the antenna from a body. Two successful antenna design approaches are reviewed: (1) using loop antennas and (2) dielectrically loaded microstrip antennas. On-body matching layers and repeaters can be used to further improve power transmission. Finally, we present the radiation characterization method for in-body antennas in spherical phantoms with a direct illumination technique using an analog fiber optic link.

“…Many techniques are available in the literature for miniaturising an antenna such as the usage of a substrate with high permittivity [1] because of the reduced effective wavelength, and operating frequency decreases thus minimising the antenna size. Secondly, by lengthening the path of current flow with the use of meandering structures [2][3][4], resonant frequency decreases which results in more compact size of the patch antenna. The third technique is the use of shorting pin [5], in which the effective size of the antenna increases, but physical dimensions get reduced as in Planer Inverted F Antennas.…”

Abstract-In this paper, a U-shaped microstrip patch antenna with meandered slots is presented. It is designed for biomedical applications to operate at 2.45 GHz. Based on the simulation experience, two designs of the patch are introduced with and without use of meandered slots. The comparative study between these two is also demonstrated. It is observed that the antenna with meandered slots shows good performance with sufficient bandwidth, low losses and is capable of use in biomedical applications. Furthermore, the proposed antenna has small size of 35 * 29 * 1.6 mm 3 , and the size of the ground is only 14% of the overall antenna size. The measured and simulated results show good agreement with each other. The antenna is fabricated on an FR4 substrate, and simulation is carried out on FDTD based Empire XCcel simulator.
