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) 射频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，例如植入传感器和执行器，还是作为利用组织特定的折射率或介电色散差异的雷达式诊断工具与现有技术相比的优点包括低光谱功率密度，减少对现有医疗设备的干扰或与生物系统相互作用的担忧，非电离辐射，低功耗和低成本。通过提高 UWB 发射器和接收器的小型化程度并降低成本，在硅上单片实现，与目前报告的工作相比，性能得到改进，¿一维和二维阵列中的新颖天线结构，¿通过新的系统概念（包括适当的信号处理）提高灵敏度和鲁棒性，¿将通信应用和类似雷达的诊断/成像纳入一个系统概念中。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密切的协同设计。天线、射频/模拟电子器件和信号处理。
