Multiband frequency selective surfaces with a modified multifractal cantor geometry

Proposal of a fractal geometry with double similarity ratio for application in frequency selective surfaces with insensitive resonance frequency as a function of cell periodicity

“…In recent times, a new group of geometries has been applied to design FSS, the fractals . More recently, studies have analyzed a variation of those fractals, the multifractals …”

UHF RFID dipole tag with modified multi‐fractal cantor arms for enhanced read range

“…The use of multi‐fractal structures in antenna design has been reported recently , which enables to increase the degrees of freedom in the design of multiband antenna structures. The self affine property of a modified multifractal cantor geometry is exploited in the design of frequency selective surface with multiband response , and the properties were found to be suitable for backscattering chipless RFID tags. However the use of multi‐fractal structures in antenna design for passive RFID tag with chip is not seen in literature.…”
