【 摘 要 】
A novel microwave sensor for real-time chloride concentration analysis is reported. The sensor response to deionised water, KCl, MnCl2and CuCl solutions at 1M and 0.1M concentration was tested. The sensing element, in the form of a silver pattern, was printed on polyimide flexible laminate substrate to suit a broad range of applications. The developed system confirmed the viability of using microwaves for real-time chloride solutions monitoring as the reflected signals represented by S11parameters were unique with clearly observed shifts in the resonant frequencies and amplitude changes when placed in direct contact with 20 μl of each solution.
