Design and realization of ultra wide-band implant antenna for biotelemetry systems

Abstract

The aim of this study is to design of a small size implantable antenna involving Industrial, Scientific and Medical (ISM) (2.4 GHz-2.48 GHz) band. The goal of designing antenna is to obtain physiological information pertaining to person. Simulation measurements of antenna were obtained in body ambient by making the design of antenna with CST Studio Suite programme. Then, in vitro measurements were performed on antenna by making an artificial material, which shows electrical features of human skin tissue, to verify measurement results. Obtained measurement results and simulative results are in accordance.

Unidirectional Uwb Magneto-Electric Antenna for Medical Telemetry

“…The idea of an outer-wall structured implantable antenna [1] was borrowed, hence a hollow structural modification for housing components of the implantable device was introduced. UWB frequency spectrum proposed by IEEE802.15-TG6 for Wireless Body Area Network applications was employed to minimize structural size and power consumption, and to improve data size and transmission rate for the medical telemetry systems [3,[10][11][12]. The proposed antenna can offer a satisfactory throughput for implantable antenna with a radiation efficiency about 50% and high gain about 2 dBi which can satisfy the requirements of the UWB medical telemetry application.…”

An implantable microstrip antenna design for MICS-band biomedical applications

“…Due to their compact size and inherent properties, SRRs have been preferred in microstrip antenna and filter applications [11][12][13][14]. Considering implantable antenna designs in the literature [1][2][3][4][5][6][7][8], the proposed low-loss and low-cost antenna has a compact size of 14 × 14 × 2.54 mm 3 (∼0.02 λ 0 × 0.02 λ 0 ) at 403 MHz, and thus the proposed design can be a good candidate for MICS-band biomedical applications.…”

“…Designing antennas that would operate in a tissue is an extremely demanding task. Factors such as tissue conductivity, impedance matching, antenna size, low power requirements, and biocompatibility play significant roles in the design [1][2][3][4][5][6][7][8]. For a realistic antenna simulation, the dielectric properties and geometry of the tissue should be taken into consideration.…”

Preparation of a Human Skin-Mimicking Gels for in Vitro Measurements of the Dual-Band Medical Implant Antenna

“…Because the antenna resides in the human body consisting of many loss media with a very high permittivity such as skin, muscle, blood, and bone. The human body has electrical properties (such as relative permittivity and conductivity) that are frequency dependent (15)(16)(17). For this reason, antenna placed in the human body is designed as based on electrical properties of the human tissue.…”

“…Sucrose, NaCl, deionized water, and carbomer were used to formulate the desired gels. The gels were prepared via mixing different percentages of different biocompatible chemicals for tissue samples in the literature (13,17,19). In the literature, agarose, a polysaccharide polymer material, was widely used to ensure the formation of gel of the mixture and in our study we used carbomer instead of agarose for this aim.…”
