The tremendous growth of wireless technologies Implantable systems are a technique of biomedical instrumentation for sensing body information or soliciting body reaction within a living organism from a location outside of the body through a wireless communication link. This dream is now a reality due to the technological advancement in electromagnetics, antenna design, wireless communications, and microwave theory leading to the design of various innovative portable wireless devices (cell phones, laptops, tablets). The next big concept is "bio-telemetry connecting patients to their doctors and hospitals at any time, any location and with any amount of monitoring and diagnostics data." Remote monitoring of the patient is possible which opens a new paradigm for health diagnosis. For this remote monitoring the capsule system is used with the help of antenna design. This book mainly focuses on the Capsule antenna design for medical applications. The analysis and design of this conformal antenna are simulated and analyzed for medical applications.
