Abstract
An electronic contact lens. In some embodiments, the electronic contact lens includes a radio antenna and radio receiver contained within the contact lens, the receiver comprising antenna impedance matching and in-phase and quadrature signal generation such that signals from the antenna are projected into in-phase and quadrature components before mixing with a local oscillator signal in the receiver. The electronic contact lens may further include electronic circuits contained within the contact lens, the electronic circuits receiving data from the radio receiver.
