n today’s scenario developing an implantable device plays a vital role in modern health care system. In most of the existing system the identification of critical situation is very difficult, subject oriented and subjective in nature. But in the proposed system the implantable device can sense bio-signals parameters such as temperature, pressure from the subject and it can be sent to the outside world. The receiver in the outside world can be placed either close to the subject or even at a distance of few meters. The device helps us to identify the critical conditions such as heart attack or stroke. The goal of our exploration is to optimize an implantable patch antenna with the defective ground structure (DGS) for biomedical application. The traditional approach to analyzing DGS relied primarily on iterative trial and error methods. This DGS can be achieved by incorporating shape errors at a level that disturbs the isolated distribution primarily due to the shape and structure of the error. Both the input resistance and the controlled antenna current are affected by the interference of the shield distribution. This allows you to adjust the excitation and propagation of the electromagnetic field throughout the substrate material. The slow wave effect of the high resistance hold zone is two characteristics of DGS. Proposed antenna is simulated using a composite material which comprises of fiber glass cloth with an epoxy resin and it is made to operate at 2.9 GHz frequency range, which is closer to the unlicensed band.
