In this study, a sensor that can distinguish ethanol+water and methanol+water mixture amount by using PCB (Printed Circuit Board) circular microstrip antenna is designed. On the ground plane of the antenna, a circular slot was made at the center and it was optimized so that the proposed sensor can work at f=3 GHz frequency and the geometrical dimensions are calculated accordingly. While performing the analysis, the placement of the liquid mixture is arranged so that the sample under test does not touch to the ground plane and the correlation between the percentages of the mixtures with the changes in the resonance frequency is determined. The resonance frequency shifts provide a frequency range of 44 MHz and this range is about 38 MHz for methanol mixtures. The changes observed in the resonance frequency are very close to linear changes which allow the determination of the percentages of both ethanol and methanol mixtures with very high precision and in real time. The designed antenna and sensor structure has low profile, low cost and also the capacity of real-time and very precise measurement.
