Chipless radio-frequency identification (RFID) sensors are not yet widespread in practical
applications because of their limited sensitivity and selectivity when compared to more …

In this paper, a highly sensitive differential Hexagonal Split Ring Resonator (HSRR) sensor
is presented operating at 5.3 GHz for permittivity characterization of organic liquids. The …

A highly sensitive electric LC resonator-derived differential sensor is proposed in this work,
with the major focus on detecting the purity of any reference dielectric material. The …

Chipless radio frequency identification (RFID) technology has been widely used in the field
of structural health monitoring (SHM), but most of the current research mainly focuses on the …

Inkjet-printing fabrication techniques can be used for the manufacturing process of chipless
