An Improvised Antenna for Wireless Implantable Medical Devices (WIMD) that support Retinal Prosthesis

Retinal diseases represent some of the top causes of blindness reported by the WHO. According to the survey planned by the Government of India in the country blindness caused by treatable diseases is about 68%, preventable diseases 25% , and remaining 7% unavoidable diseases. An artificial vision system will help to reduce the percentage of blindness.This paper presents an improvised design of an antenna for wireless implantable medical devices (WIMD) that support retinal prosthesis. The proposed microstrip patch antenna design has a ground, main radiator, and parasitic structure with a modified square ring, mitered cross, and splitting four arms with an emptied channel that features circular polarization and Industrial, Scientific, and Medical(ISM) band working frequency supporting high data rate could improve the image perception capability. Biocompatible material Roger 6010 reduces the size and toxicity of the implant.The proposed model was designed and simulated using High-frequency simulation software (HFSS). A scaled version of the prototype antenna was fabricated with a flexible copper sheet, it was found that the prototype antenna embedded in minced pork results satisfactorily matched the simulated version.
