Abstract
An oscillation device comprises a substrate and a plurality of resonance structures arranged on the substrate to resonate electromagnetic waves. Each of the plurality of resonance structures has a negative differential resistance device for generating electromagnetic waves, a first conductor arranged electrically in contact with the negative differential resistance device and a second conductor arranged electrically in contact with the negative differential resistance device and disposed on the opposite side to the first conductor with respect to the negative differential resistance device. Adjacently located resonance structures of the plurality of resonance structures are interconnected by means of a metal part adapted for capacitive coupling with the first conductors thereof. The plurality of resonance structures are arranged so as to be separated from each other at least by a distance not greater than a wavelength of electromagnetic waves to be oscillated by them.
