    • An antenna structure for an implantable medical device (IMD) is provided that includes an antenna embedded within a structure derived from a plurality of discrete dielectric layers. An array of electrodes are connected to the antenna structure and arranged for applying a bias across selected segments of the dielectric layers for altering the performance characteristics of the antenna. The bias applied by the array of electrodes can be selected to provide desired impedance matching between the antenna and the surrounding environment of the implant location to mitigate energy reflection effects at the transition from the antenna structure to the surrounding environment, to provide beam steering functionality for the antenna, or to alter the gain of the signals received by the antenna. IMD is configured to monitor received signal characteristics (e.g., RSSI, EVM or bit error rate) and alter material properties of the dielectric material through biasing to control antenna performance.
    • 提供了一种用于可植入医疗装置(IMD)的天线结构,其包括嵌入在由多个离散电介质层衍生的结构内的天线。 电极阵列连接到天线结构,并布置成用于在电介质层的所选段上施加偏置,以改变天线的性能特征。 可以选择由电极阵列施加的偏置以在天线与植入位置的周围环境之间提供期望的阻抗匹配,以减轻在从天线结构向周围环境的转变时的能量反射效应,以提供用于 天线,或改变由天线接收的信号的增益。 IMD被配置为监视接收的信号特性(例如,RSSI,EVM或误码率),并通过偏置来控制天线性能来改变电介质材料的材料特性。
