In the present scenario in the field of human health service and body worn application, the major concern is to detect the actual cause of the pain in human body. In this paper the design and proper shape of antenna for a particular body part like knee, elbow or any other joints are presented with the optimized characteristics and comparison between spiral and Hilbert antenna so that the proper parameters like temperature, lubrications or any damage can be analysis. And for security service, the concern is for small size and minimum loss. Now these antenna devices transmit the physiological data from the body for health purpose and for security purpose and desired information will be transmitted from the body to the peripheral device. These two antennas are designed at operating/resonant frequency of 500 MHz with main objectives of minimum size, minimum error, less power consumption and proper shape of antenna to fit the body part after calculating the SAR value.
