Patent abstract
An electromagnetic-wave oscillator includes a substrate, an EMW oscillating unit including a gain portion, an EMW resonance portion, an EMW radiating portion, and a ground (GND) portion, and a supplying unit for supplying electric power to the EMW oscillating unit. The ground portion regulates a predetermined reference electric potential for the gain portion, the EMW resonance portion, and the EMW radiating portion. The EMW oscillating unit is disposed on a first surface of the substrate. The supplying unit is disposed on a second surface of the substrate extending on an opposite side to the first surface. The EMW oscillating unit and the supplying unit are electrically connected via a penetrating electrode formed in the substrate.
