Retinal Prosthesis has developed to a more advanced stage with the support of advancing technologies. However, there have not been enough details about the wireless mechanism within the system even though it is accountable for the information transmission from the camera to the electrodes and also the complexity of the process itself due to the challenging environments. This paper will discuss about a design of high performance antenna that suits the challenging condition of the implantable devices. Its performance will then be compared with similar antennas that have been proposed or built previously.
