MINIATURIZED ULTRA-WIDEBAND ANTENNA SYSTEM FOR MULTIPLE BIO-TELEMETRIC APPLICATIONS

摘要

The present disclosure relates to an implantable communication device with an ultra-wideband antenna, and the implantable communication device according to an exemplary embodiment of the present disclosure includes: a sensor unit which obtains a biological signal in a body at a site where the implantable communication device is implanted; and an ultra-wideband antenna which transmits the obtained biological signal to the outside of the body. In this case, the ultra-wideband antenna includes: a ground patch which includes a first slot, a second slot, and a feed hole; a first dielectric layer which is formed on the ground patch; a radiation patch which is positioned on the first dielectric layer, and includes a third slot having a spiral shape, and a feed line; and a second dielectric layer which is formed on the radiation patch, the feed line is connected to a lower surface of the radiation patch, and vertically penetrates the feed hole, one end of the first slot and one end of the second slot are connected to each other, and a shape of the second slot depends on a shape of the third slot.
