چکیده :

Microwave sensors are suitable candidates for point-of-care (POC) devices due to the advantages they offer over other sensing methods. These sensors are low cost, sensitive, small, and reliable. However, the need to use bulky and expensive vector network analyzers limits their application in POC systems. Here we present a simple measuring system to tackle this problem, allowing the integration of microwave sensors with POC testing. The performance of the system is validated by measuring solutions of water-glucose and water-isopropyl alcohol with different concentrations. It is shown that the system can distinguish different solutions by measuring the phase shift and power attenuation in transmission coefficient of a microwave sensor.
