Abstract
Radio frequency (RF) isolators are described, coupling circuit domains operating at different voltages. The RF isolator may include a transmitter which emits a directional signal toward a receiver. Layers of materials having different dielectric constants may be arranged to confine the emission along a path to the receiver. The emitter may be an antenna having an aperture facing the receiver.
