Abstract

A new double-sided spiral split-ring resonator (DSS-SRR) is proposed and implemented as a near field sensor for measuring the relative permittivity ε_r of unknown materials. This sensor is based on the measurement of the resonance frequency shift of a tapered microstrip line fed DSS-SRR. In contrast to other sensors based on the use of conventional SRRs, the proposed sensor requires a very small amount of sample due to its miniature sensitive area, and it provides a high sensitivity with lower frequency due to the small electric size of the DSS-SRR. Examples of operation of the sensor with four dielectric samples are presented to reveal the potentiality of the DSS-SRR for biosensing applications.
