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.
近年来，电磁波在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。在这方面，遥测技术可以对生理机能进行微创式监测，提高舒适度和患者护理水平，并显著降低医院成本。为了通过射频信号（RF）协助进行骨质密度分类，以便以后诊断骨质疏松症，2018 年开发了 Osseus。该设备是应用软件、电气、电子、计算和生物医学工程等多个领域的技术和概念的结合，其成本低、易于被民众获取、且非侵入式。然而，在评估过程中，发现了一些可以提高 Osseus 运行稳定性的改进措施。有人提议改进 Osseus 使用的天线，使其小型化，提高 RF 信号的接收能力，并提高设备运行的稳定性。随后，制造了两个天线，其中一个天线是作为第二个天线的项目，即天线阵。该天线阵在与应用相关的辐射参数方面有显著的改进，是替代 Osseus 目前使用的天线的候选者。
