Microstrip antenna and implantable medical system adopting same

Abstract

The invention discloses a microstrip antenna and an implantable medical system applying the same. The microstrip antenna comprises an antenna radiation unit and a PCB substrate; the antenna radiationunit is positioned on the PCB substrate; the antenna radiation unit comprises a feed point, a feed microstrip line, a short circuit point, a ground microstrip line and a radiation body; the feed pointand the short circuit point are connected with the ground microstrip line through the feed microstrip line; the radiation body is connected to the connecting position of the feed microstrip line andthe ground microstrip line; and the feed point, the feed microstrip line, the short circuit point, the ground microstrip line and the radiation body form a PIFA antenna. The implantable medical systemcomprises an in-vitro program controller, wherein the in-vitro program controller comprises the above-mentioned microstrip antenna. Compared with the prior art, the microstrip antenna and the implantable medical system applying the same have the advantages of high matching degree, low loss, compact structure, simple processing, low contractions cost, high gain, high omnidirectivity and the like.

Description

technical field [0001] The invention belongs to the field of implanted medical devices, in particular to a microstrip antenna and an implanted medical system using the antenna. Background technique [0002] Implantable medical systems generally consist of two parts: implantable medical devices and in vitro program-controlled equipment. The data exchange between implantable medical devices and in vitro program-controlled devices is a two-way wireless data transmission. On the one hand, in vitro program-controlled devices need to send program-controlled Feedback information and measurement diagnostic information sent by the device. In vitro program-controlled equipment includes doctor program controllers and patient program controllers. Among them, the patient program controller is a device equipped for the patient to control the switch or adjust the implanted medical device in the body according to his own situation. The patient can usually only adjust within the adjustment...
