Abstract
A RF antenna or sensor has a substrate, a resonator operable at UHF disposed on the substrate, the resonator preferably having a quartz bar or body with electrodes disposed on opposing major surfaces thereof and with a magnetostrictive material disposed on or covering at least one of the electrodes. A pair of trapezoidal, triangular or wing shaped high permeability pole pieces preferably supported by that substrate are disposed confronting the resonator, one of the pair being disposed one side of the resonator and the other one of the pair being disposed on an opposing side of said resonator, the pair of high permeability pole pieces being spaced apart by a gap G, the resonator being disposed within that gap G. The size of gap G is preferably less than 100 μm.
