Applications on electromagnetic waves in the field of biotelemetry have increased in the latest years, being used to prevent, diagnose, and treatment of several diseases. In this context, biotelemetry allows minimally invasive monitoring of the physiologic, improving comfort and patient care and significantly reducing hospital costs. Aiming to assist the mineral bone density classification, through a radio frequency signal (RF), for a later diagnosis of osteoporosis, Osseus was proposed in 2018. This equipment is a combination of the application of techniques and concepts of several areas such as software, electrical, electronic, computational, and biomedical engineering, developed at a low cost, with easy access to the population, and non-invasive. However, when placed on evaluation, potential improvements were identified to increase the stability of Osseus operation. It is proposed the implementation of improvements in the antennas used by Osseus, aiming its miniaturization, improvement in the reception of the RF signal, and better stability of the equipment's operation. Then, two antennas were built, one of which was used as a project for the second, which is an array. The array showed significant improvements in the radiation parameters relevant to the application, being a candidate to replace the antennas currently in use at Osseus.

OSSEUS 中使用的天线增益和波束宽度对骨质疏松症筛查过程的影响

近年来,电磁波在生物遥测领域的应用有所增加,被用于预防、诊断和治疗多种疾病。在这种情况下,生物遥测允许对生理进行微创监测,提高舒适度和患者护理,并显着降低医院成本。为了辅助矿物质骨密度分类,通过射频信号(RF),为后期骨质疏松症的诊断,Osseus于2018年被提出。 该设备结合了软件、电气、电子、计算和生物医学工程,以低成本开发,易于接触人群,并且是非侵入性的。但是,在进行评估时,确定了潜在的改进,以提高 Osseus 操作的稳定性。建议对 Osseus 使用的天线进行改进,旨在实现其小型化,改善 RF 信号的接收,以及更好的设备运行稳定性。然后,建造了两根天线,其中一根用作第二根天线的项目,这是一个阵列。该阵列在与应用相关的辐射参数方面表现出显着改善,是替代 Osseus 目前使用的天线的候选者。其中一个用作第二个的项目,这是一个数组。该阵列在与应用相关的辐射参数方面表现出显着改善,是替代 Osseus 目前使用的天线的候选者。其中一个用作第二个的项目,这是一个数组。该阵列在与应用相关的辐射参数方面表现出显着改善,是替代 Osseus 目前使用的天线的候选者。
