Japanese Patent JP7419170

B2

Embodiments described herein include a chipless patterned conductor, comprising one or more glyphs. Each glyph comprises a disk and a ring structure including at least one ring surrounding the disk. One or more of a spacing between the disk and the at least one ring and a width of the at least one ring is configured to determine a characteristic resonant frequency of the glyph. At least one notch is disposed in at least one of the disk and at least one ring of the ring structure. The at least one notch is configured such that the magnitude of resonances in the glyph are dependent on polarization direction.
