We have presented the design methodology along with detailed simulation and measurement results for optimizing a multiband transcutaneous wireless link for high-performance implantable neuroprosthetic devices. We have utilized three individual carrier signals and coil/antenna pairs for power transmission, forward data transmission from outside into the body, and back telemetry in the opposite direction. Power is transmitted at 13.56 MHz through a pair of printed spiral coils (PSCs) facing each other. Two different designs have been evaluated for forward data coils, both of which help to minimize power carrier interference in the received data carrier. One is a pair of perpendicular coils that are wound across the diameter of the power PSCs. The other design is a pair of planar figure-8 coils that are in the same plane as the power PSCs. We have compared the robustness of each design against horizontal misalignments and rotations in different directions. Simulation and measurements are also conducted on a miniature spiral antenna, designed to operate with impulse-radio ultra-wideband (IR-UWB) circuitry for back telemetry.
我们提出了设计方法，并给出了详细的仿真和测量结果，以优化用于高性能植入式神经假体设备的多频带经皮无线链路。我们利用三个单独的载波信号和线圈/天线对进行功率传输、从外部向体内的前向数据传输以及相反方向的反向遥测。通过一对面对面的印刷螺旋线圈（PSC）以 13.56 MHz 的频率传输功率。针对前向数据线圈评估了两种不同的设计，这两种设计都有助于最小化接收数据载波中的功率载波干扰。一种是一对垂直线圈，它们缠绕在功率 PSC 的直径上。另一种设计是一对平面 8 字形线圈，它们与功率 PSC 在同一平面上。我们比较了每种设计对不同方向的水平不对齐和旋转的稳健性。还对微型螺旋天线进行了仿真和测量，该天线设计用于与脉冲无线电超宽带（IR-UWB）电路配合使用，以进行反向遥测。
