Ultra-wide band (UWB) RF techniques offer well-recognized advantages for biomedical applications, both in communication links, e.g, with implanted sensors and actuators, or as a radar-like diagnostic tool exploiting tissue-specific differences in refractive index or dielectric dispersion characteristics. Advantages over existing techniques include a low spectral power density reducing concerns over interference with existing medical equipment or interactions with biological systems, non-ionizing radiation, low power consumption, and low cost. The proposed research project targets significant performance improvements over currently reported work throughincreased miniaturization and reduced cost of the UWB transmitters and receivers, realized monolithically on Silicon,¿ novel antenna structures in one- and two-dimensional arrays,¿ increased sensitivity and robustness through new system concepts including appropriate signal processing,¿ inclusion of communication applications and radar-like diagnostic/imaging in one system concept.Together with biomedical researchers and clinical specialists from the University of Ulm s University Hospitals, promising applications are being identified. They will guide and benefit from the close co-design of antenna, RF/analog electronics, and signal processing.

超宽带（UWB）RF技术为生物医学应用提供了公认的优势，无论是在通信链路中，例如，与植入的传感器和致动器，还是作为利用组织特异性折射率或介电色散特性差异的雷达样诊断工具。与现有技术相比的优点包括低光谱功率密度，减少了对现有医疗设备的干扰或与生物系统的相互作用的担忧，非电离辐射，低功耗和低成本。拟议的研究项目的目标是通过增加UWB发射机和接收机的小型化和降低成本，在硅上单片实现，一维和二维阵列中的新颖天线结构，通过包括适当信号处理在内的新系统概念提高灵敏度和鲁棒性，在一个系统概念中包含通信应用和雷达类诊断/成像。与乌尔姆大学医院的生物医学研究人员和临床专家一起，正在确定有前途的应用。他们将指导并受益于天线、RF/模拟电子和信号处理的紧密协同设计。
