Abstract:
1. A sensor for sensing a measurand comprising: a meander-shaped coplanar waveguide with a first surface and a second surface opposite to the first surface; air-bridges at bends of the meander-shaped coplanar waveguide; a first structure with a first periodically varying dielectric characteristic, the first structure being arranged on the first surface of the coplanar waveguide; and a second structure with a second periodically varying dielectric characteristic, the second structure being arranged on the second surface of the coplanar waveguide, wherein a unit-cell of the first and second structures with periodically varying dielectric characteristics is dimensioned such that the sensor has a frequency dependent transfer behavior with at least one transfer minimum, and wherein the sensor is implemented such that the measurand influences the first periodically varying dielectric characteristic of the first structure or the second periodically varying dielectric characteristic of the second structure, or a relation between the first structure and the second structure.
