Flexible ultra-wideband antenna with incorporated metamaterial structures- multiple notches for data encoding of chipless RFID application

A coplanar waveguide ultra - wideband antenna with in corporated metamaterial structure operating from 3.0-12.0 GHz is designed for data encoding for chip less RFID. A slotted modified complementary split ring resonator is introduced into the ultra - wideband antenna to produce multiple band-notches characteristics . To achieve encoding of 10 - bits data, 5 MCSRRs are proposed with three slotted MCSRR in the radiator and three slotted MCSRR in the ground plane. This technique is suitable for creating a compact and a high capacity chipless RFID tag.
