Claim:
1. A sensor for sensing at least a physical property of an environment, the sensor comprising a microwave resonator having a top conductive layer, a bottom conductive layer and a substrate layer made of a first dielectric material sandwiched therebetween, a fence electrically connecting the top conductive layer to the bottom conductive layer across the substrate layer and enclosing at least one resonance cavity, at least one microwave signal port across the fence, at least one sensing portion having a second dielectric material functionalized to the physical property of the environment, the second dielectric material extending across the conductive layers and the at least one resonance cavity and being exposed to the environment during use of the sensor, the microwave resonator having at least one resonance frequency being dependent of the exposure to affect a microwave signal resonating therein.
