Document Type and Number:
WIPO Patent Application WO/2015/129910
Kind Code:
A3
Abstract:
An oscillation element that oscillates an electromagnetic wave includes a negative resistance element (101) and a resonator (110) including a first conductor (106) and a second conductor (104), in which the negative resistance element and the resonator are arranged on a substrate (105), 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 f1of the resonator satisfies f1= 1/(2π√(L1C)}, and f1< C0/[d√{(1+εr)/2}]. The resonator may be of distributed constant type, wherein the resonator includes a first conductive layer (102), a second conductive layer (103), and a third conductive layer, wherein the first conductive layer is short-circuited to the second conductive layer, wherein the negative resistance element is connected to the first conductive layer and the third conductive layer, and wherein the second conductive layer and the third conductive layer are arranged opposite each other and are also capacitively coupled to each other to form a capacitance (C).
