Abstract:
An oscillation element that oscillates an electromagnetic wave includes a negative resistance element and a resonator including a first conductor and a second conductor, in which the negative resistance element and the resonator are arranged on a substrate, the negative resistance element is electrically connected to the first conductor and the second conductor, the first conductor and the second conductor are capacitively coupled to each other, and when a capacitance between the first conductor and the second conductor is set as C, an inductance of the first conductor and the second conductor is set as L1, a speed of the oscillated electromagnetic wave in vacuum is set as C0, a relative dielectric constant of the substrate is set as εr, and a diagonal line length of the substrate is set as d, a series resonant frequency f1 of the resonator satisfies f1=1/{2π√(L1C)}, and f1<C0/[d√{(1+εr)/2}].
