The invention discloses an antenna, an implantable medical device and an implantable medical system. An antenna for an implantable medical device includes an antenna body and a PCB dielectric substrate. The antenna body is suspended on an upper layer of the PCB dielectric substrate, and the antenna body includes an antenna radiating unit, a short circuit point, a feeding point, and two ends respectively connected to the short circuit point. And the first line segment of the feed point, the feed point is connected to the antenna radiating unit. An implantable medical device having a PIFA antenna of the aforementioned MICS band. An implantable medical system comprising the implantable medical device described above. The invention makes the implantable medical device more compact, enabling it to achieve higher efficiency and longer distance communication with the external program control device. |
