    (University of Oum El Bouaghi, 2021) Halfaya, Ahmed; Lashab, Mohamed; Salmi, Salah; Soufi Youcef
    In this paper a Microstrip line coupled double concentric elliptical complementary split-ring resonator etched in the ground plane is used to create a sensor. The operating frequency of presented metamaterial sensor is from 1Ghz to 2 Ghz .The sensor is designed and simulated with the commercial software CST Studio Suite . The liquid sample's complicated dielectric permittivity affects the resonance frequency and bandwidth. We can build an empirical link between sensor resonance and sample permittivity using data collected from simulations. the resonance frequency is shifted from 1.50 down to1.49 Ghz. On the basis of variations in the resonance frequency and peak attenuation of the transmission response [ l S21 l max] on resonance the sensor estimates the complex permittivity of a liquid. The proposed sensor is easily to fabricated and reusable resonator.
