Stopband split ring resonator (SSRR) is presented in this paper for measuring complex permittivity of liquid with different position of microfluidic channel operates at resonant frequency of 1 GHz. The sensor was fabricated and microfluidic channel is located in the gap groove with two different positions of the carrier where the electric field is as large as possible. The sensor has been tested with several solvents to verify its sensitivity where the electric field interacts with the liquid filled in a quartz tube and hence alter the SRR behavior. The electromagnetic properties (complex permittivity) of the solvent can be extracted from shift in the resonant frequency of the resonator due to perturbation phenomenon.
