Implantable antenna for use with an implantable medical device

摘要: For wireless data exchange between an implantable medical device and extracorporal unit by means of antenna arrangement for communicating radio frequent signals, the includes a patch plane having perimeter, ground electrically conducting material dielectric substrate filling volume plane. The has area which is larger than located in relation to such that perpendicular projection onto falls entirely within A grounding member connects at first segment perimeter. comparatively high relative permittivity extends well-defined distance outside with respect least one second non-conducting region thus created therefore only relatively small amount electromagnetic losses will occur this region.
