Conformal Antenna Film

SoftAlloy™ is a soft-magnetic thin film sputtered onto a flexible substrate primarily to create the next generation of conformal permeable broadband antennas in HF, VHF, UHF, and Sat Comm frequency ranges. These magneto-dielectric antennas operate using the current induced in the complex permeability of their own construction materials. Antennas made of this material allow for new designs of antennas, as a natural evolution of the ferrite dipole, these materials solve the problems that conventional metal- and-dielectric antennas face.
