US Patent 12095140 Flexible antenna for a wireless radiation dosimeter

A flexible antenna for a wireless X-ray dosimeter chip is described. The flexible antenna includes a dipole antenna associated with an artificial magnetic conductor, wherein the artificial magnetic conductor includes: a top layer configured to partially act as a reflective surface; a bottom conductive ground plane layer configured to prevent propagation of incident electromagnetic waves and to reflect the electromagnetic waves; and a middle layer including a foam material configured to provide an appropriate phase delay between incident electromagnetic waves from the top layer and the reflected waves from the ground plane layer.
