Implanted antenna applied to ISM frequency band

The invention provides an implanted antenna applied to an ISM frequency band, and relates to the technical field of medical equipment, and the implanted antenna comprises a dielectric substrate (100), and a first concentric-square-shaped metal strip (201) and a second concentric-square-shaped metal strip (202) which are connected are printed on the upper surface of the dielectric substrate (100); a rectangular metal sheet (300) is printed at the end part of the lower surface of the dielectric substrate (100); a feeder line is printed on the dielectric substrate (100) along a long edge, and power is supplied to the first clip-shaped metal strip (201) through the feeder line; a feed point is provided between the end of the feed line and the rectangular metal sheet (300). The antenna provided by the embodiment of the invention can cover an ISM 2.4 GHz frequency band in muscles, human tissues with parameters similar to those of a muscle medium and fat with parameters obviously different from those of the muscle m
