Abstract

The invention discloses a microstrip antenna and an implanted medical system using the antenna. The microstrip antenna includes an antenna radiation unit and a PCB substrate. The antenna radiation unit is located on the PCB substrate. The antenna radiation unit includes a feed point, a feed microstrip line, a short circuit point, a ground microstrip line and a radiation body, a feed point and a short circuit point The feeder microstrip line and the grounding microstrip line are connected, the radiation body is connected to the junction of the feeding microstrip line and the grounding microstrip line, the feed point, the feeding microstrip line, the short-circuit point, the grounding microstrip line and the radiation The body forms a PIFA antenna. The implantable medical system includes an external program controller, and the external program controller includes the aforementioned microstrip antenna. Compared with the prior art, the microstrip antenna and the implanted medical system using the antenna have the advantages of high matching degree, small loss, compact structure, simple processing, low cost, high gain, good omnidirectionality 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...
