Optimal permeable antenna flux channels for conformal applications

摘要

Permeable antennas are presented. In embodiments, a permeable antenna may include a flux channel comprising a permeable material inside a trough in a conducting ground plane, the trough having a depth d and a width b; and a capacitive shunt admittance provided at the mouth of the trough. In embodiments, the capacitive shunt admittance may be one of: a slitted conducting plane or a single feed parallel solenoid, fed by a transmission line at a center loop. In embodiments, the conducting material may be anisotropic, and may include a ferromagnetic laminate comprising alternating thin metal films with thin insulating dielectrics. Related methods of providing permeable antennas are also presented.
