Abstract: Deformable magnetic antennas are provided to include a plurality of flexible magnetic antenna layers stacked to form a layered magnetic antenna structure that is bendable. Each flexible magnetic antenna layer includes a magnetic material that confines a magnetic field to concentrate a magnetic flux of the magnetic field inside the magnetic antenna layer. A lubricating material is applied between adjacent flexible magnetic antenna layers to allow adjacent magnetic layers to move relative to one another when the layered magnetic antenna structure is bent so as to reduce a stress in each flexible magnetic antenna layer caused by bending the layered magnetic antenna structure.

Abstract: Magnetic antenna techniques and devices are disclosed for operating at an RF or microwave frequency by using a magnetic antenna structure having a spatially varying property that varies spatially from one location to another location in at least a portion of the magnetic antenna structure. Such a spatially varying property can be reflected in various ways, e.g., a spatially varying geometry profile in part of or the entirety of the magnetic antenna structure, a spatially varying antenna material property in a spatially uniform geometry or a spatially varying geometry. The disclosed technology also provides magnetic antenna structures based on splitting the componentry for transmission and reception so that each can be individually optimized.
