1. A device for detecting at least one analyte in a liquid, the device comprising:

  • a sensor having an antenna including;

    a substrate comprising first and second opposite faces,a ground plane arranged on the first face of the substrate, andat least one metallic part located on the second face of the substrate, at least some of the metallic part covered with a molecularly imprinted polymer layer comprising a silica or acrylate base that interacts with an analyte to produce a variation in the antenna characteristics within the microwave frequency range;

    wherein the metallic part comprises three internal strips forming an isosceles triangle and two external strips which extend symmetrically from first and second corners of the isosceles triangle with respect to the median extending through a third corner of the isosceles triangle; and

    a vector network analyzer that emits an electromagnetic wave at a frequency between 300 MHz and 300 GHz, the vector network analyzer emitting an incident wave to the antenna, receiving a reflected wave from the antenna, and measuring the ratio between the reflected wave and the incident wave as a function of frequency.
