Abstract
A sensor includes a planar T-resonator and an oscillator. The planar T-resonator can be a branched T-resonator with at least two symmetrical branches coupled to a stub. The oscillator has an input coupled to the planar T-resonator and an output. The oscillator has a negative resistance within a predetermined frequency range. The oscillator can be configured so that it has an input phase approximately equal to a phase of the planar T-resonator over a majority of the predetermined frequency range.
