Abstract
A dielectric resonance element comprises a dielectric member integrally formed and composed of first and second plate portions which intersect each other such that respective center lines of the plate portions are coincident with each other. The first and second plate portions cause TE01δ resonance modes to develop, in which the electric field vectors of the TE01δ resonance modes are turned in the in-plane directions of the plate portions.
Claims20
A dielectric resonance element comprising:
- a dielectric member having a first plate portion and a second plate portion, the first and second plate portions intersecting each other and having respective center lines which are coincident with each other,
- wherein TE01δ mode electromagnetic fields are generated in the first and second plate portions, respectively, such that electric field vectors are turned in respective in-plane directions of the first and second plate portions.
An oscillator device comprising:
- two oscillators, each oscillator containing a line, a positive element connected to one end of the line, and a dielectric resonance element connected to an intermediate point of the line,
- wherein each of the dielectric resonance elements are disposed on a substrate having the lines and the positive elements formed thereon, and electromagnetic fields of two coupling modes generated between two TE01δ modes of the dielectric resonance elements are coupled to the lines of the two oscillators, respectively, each of the dielectric resonance elements having a first plate portion and a second plate portion, the first and second plate portions intersecting each other and having respective center lines which are coincident with each other.
A dielectric resonance element comprising:
- a dielectric member having integrally formed first and second substantially square plate portions which intersect each other,
- wherein TE01δ mode electromagnetic fields are generated in the first and second flat plate portions, respectively, such that electric field vectors are turned in respective in-plane directions of the first and second plate portions, respectively.
