- Abstract
The main objective of this study is to develop a new fractal antenna with radio characteristics for the detection of the concentration of fructose in water for uses in biosensors. For this, we have designed and studied three prototypes of fractal antennas operating in different working bands. For the detection of the concentration of fructose, we used, a small container placed on the upper face of the antenna. This reception and each time filled with a different concentration of fructose, the concentrations modify the radioelectric behavior of the fractal antenna which is reflected by a shift/mismatch of the operating bands (resonance frequencies) of the different prototypes. After analysis and study of measurement and simulation results, a correspondence between the frequency behavior with or without fructose concentration allows us to deduce a correspondence table between the fructose concentrations and the reflection coefficient of the antenna (resonance frequency). The experimental study proved that our realized sensor exhibit and miniaturization (electrical size of λ0/8), high sensitivity and good linearity of the sensor with two methods: frequency method with average sensitivity of 0.132 and S11 parameter method with average sensitivity of 0.1862. The proposed structure showed an ability to detect a low concentration fructose. These aqueous solutions represented in the form of known sugars such as fructose added in low concentration give realization of agro-food and biomedical sensor.
