Abstract
Intraocular pressure is an important aspect in the evaluation of patients at risk from glaucoma. Glaucoma is an ocular disorder that results in the damage of optic nerve, often associated with increased aqueous pressure in the eye. Wireless technology reduces discomfort, risk of infection and monitor patients in remote places by providing timely health information. In order to transmit the ocular pressure through the wireless media a proposed design of wireless contact-lens antenna has been designed. The contact-lens coupled structure antenna was designed for the betterment of reflection co-efficient and for minimising the density of materials by gap-coupled configuration in comparison with the conventional on-lens loop antennas. The return loss of the designed contact lens antenna was 21 dB at 2.6 GHz with a diameter ranging from 14 to 15 mm. The simulation result of designed antenna return loss was obtained using advanced design system. The measured antenna return loss, radiation pattern and current distribution will be demonstrated in this paper, which are suitable for application of wireless ocular physiological monitoring.
