Abstract

PURPOSE:To obtain a substrate module for a dielectric resonator capable of being surely combined without using a specific combining circuit by forming a conductor face and a circuit pattern on a prescribed face of a circuit substrate so that the circuit pattern is magnetically combined with semicircular dielectric. CONSTITUTION:The conductor face 1 consisting of a thin film metal or the like and the conductor circuit pattern 3 are respectively formed on the rear face and front face of the plane circuit substrate 10, the conductor face 1 on the rear face of the substrate 10 is driven as the image face of semicircular dielectric 2 and the circuit pattern 3 on the front face of the substrate 3 is magnetically combined with the dielectric 2. In said constitution, the conductor face 1 on the rear face of the substrate 10 is driven as the mirror image face of the dielectric 2 fixed on the surface of a non-conductor on the substrate 10 and the conductor is resonated in a prescribed mode. Since the pattern 3 is formed on the surface of the substrate 10 which is not the mirror image face, the pattern 3 surely cuts off the line of magnetic force of the dielectric 2 so as to be magnetically combined with the dielectric 2.

Description

[Detailed Description of the Invention] [Summary] A dielectric resonator used in the microwave frequency band, in particular a dielectric resonator made of a semicircular dielectric whose conductor surface is a mirror image surface, on a planar circuit board. Regarding the board mosule of a dielectric resonator that is mounted on a circuit board and combined with other circuit patterns on the board to form a module, even if the circuit patterns of other conductors of the dielectric resonator are on the circuit board, they are mirror images. The purpose of this is to create a board module for a cable resonator that is not a flat surface but must be coupled with a semicircular dielectric 2 that operates on the mirror image principle. A circuit pattern of a conductor is provided on the front surface of the circuit board, and the conductor surface on the back surface of the circuit board operates as a mirror image surface of a semicircular dielectric, so that the circuit pattern of the conductor on the surface of the circuit board is always connected to the semicircular dielectric and the magnetic field. It is structured so that it connects.

[Industrial application field]

The present invention relates to a dielectric resonator used in the microwave real wave band, and in particular, a dielectric resonator to which a mirror image principle is applied is mounted on a flat substrate of a micro integrated circuit (formerly C). The present invention relates to a dielectric resonator substrate module that is combined with a circuit pattern to form a module.

[Conventional technology]

As shown in Fig. 3, a dielectric resonator applying the mirror image principle is constructed by attaching a semicircular dielectric material 2A, which is half of a circular dielectric material, to an MTC substrate 1.
It is fixed onto a flat conductor surface IA such as a metal thin film on the surface of 0A, operates with the conductor surface IA as a mirror image surface, and resonates equivalently in the TEo+δ mode.

In this case, the lines of electric force of the electric field in the resonant semicircular dielectric body 2A are as shown by the solid line in the figure, and the lines of magnetic force of the magnetic field are perpendicular to the electric field and become zero at the conductor surface 1A, as shown by the dotted line in the figure.

In the conventional dielectric resonator substrate module shown in FIG. ^
Combined with MIC Moji j. - It has a structure that provides a wall.

[Problems to be Solved by the Invention] The substrate mosicole of the conventional dielectric resonator shown in Fig. 3 is as follows.
As mentioned above, the semicircular dielectric 2A resonates with the planar conductor surface 1A fixed thereon as a mirror image surface, and generates a magnetic field with lines of magnetic force as indicated by the dotted lines in the figure. If the circuit pattern 3A of the other conductor on the MIC board 10A that is combined to form a module is on the same plane as the conductor surface {A, the conductor of the circuit pattern 3A does not cut the lines of magnetic force of the magnetic field. There is a problem that there is no magnetic field coupling with the semicircular dielectric body 2 and no coupling occurs. The present invention provides a dielectric resonator in which a circuit pattern of a semicircular dielectric and another conductor is always coupled to a semicircular dielectric that operates on a mirror image principle even if it is on a planar old C circuit board. The objective is to provide a substrate model for the following.

[Means for solving the problem] As shown in FIG. 1, the problem is to provide a conductor surface 1 made of a thin film metal or the like on the back surface of the MIC circuit board 10, and to form a semicircular conductor surface 1 on the back surface of the old C board. A mirror image surface 3 of the dielectric 2 is formed, and a conductor circuit pattern 3 is formed on the surface of the MIC substrate 10.
This problem is solved by the structure of the present invention in which a is provided and magnetically coupled to the semicircular dielectric body 2.

In the principle diagram of FIG. 1 showing the basic configuration of the dielectric resonator substrate module of the present invention, (2) is the conductive surface on the back side of the planar circuit board 10, which acts as a mirror image surface of the semicircular dielectric 2. do.

2 is fixed to the non-conductor surface of the circuit board 10 and operates with the conductor surface 1 on the back surface as a mirror image surface, equivalently TEo
It is a semicircular dielectric that resonates in Iδ mode.

3 is a circuit pattern of a conductor on the surface of the circuit board 10, in which the semicircular dielectric 2 does not form a mirror image surface of the semicircular dielectric 2.
The structure is such that the magnetic field is coupled to the magnetic field.

[Effect]

The conductive surface 1 on the back side of the circuit board 10 operates as a mirror image surface of the semicircular dielectric 2 fixed to the non-conducting surface of the circuit board 10, and the semicircular dielectric 2 resonates equivalently in the TEo+δ mode. do. Since the conductor circuit pattern 3 is located on the surface of the MIC substrate 10 which is not a mirror image surface, it necessarily cuts the lines of magnetic force of the magnetic field of the semicircular dielectric 2 and is magnetically coupled to the semicircular dielectric 2. Therefore, in the dielectric resonator substrate module of the present invention, the problem is solved because the circuit pattern 3 of the conductor on the surface of the circuit board 10 is coupled to the semicircular dielectric 2 that operates on the mirror image principle.

? Embodiment] The principle diagram in FIG. 1 shows the structure of a dielectric resonator substrate module according to an embodiment of the present invention, and its operation has already been explained.

FIG. 2 shows the structure of another embodiment of the present invention, in which a semicircular dielectric 2 is attached to a part 10 of a substrate 10,
Part of the circuit board 10. Although there is no metal conductor on the front or back side of the MIC board 10, the part 10 of the MIC board 10
I is fixed in contact with the surface of a metal casing 20 that houses the entire substrate 10, and the surface of the metal casing 20 is used as a mirror image surface to cause the semicircular dielectric 2 to resonate equivalently in the TEo+δ mode. A conductor circuit pattern 3 is provided on the surface of the other part 10 of the MrC substrate 10 (4.1).

In the case of the embodiment shown in FIG. 2, the mirror image surface of the semicircular dielectric 2 is the conductive surface of the metal housing 20 on the back surface of the circuit board IO, and the conductor circuit pattern 3 is the mirror image surface of the semicircular dielectric 2. The part 10 of the circuit board 10 that does not become . , the conductor circuit Bakun 3 necessarily cuts the lines of magnetic force of the magnetic field of the semicircular dielectric 2 and magnetically couples with the semicircular dielectric 2.

Therefore, in both the dielectric resonator substrate modules of the embodiments shown in FIG. 1 and FIG. There is no problem since they are combined.

Since the MIC module can be connected only by using the MIC module, the number of parts of the MIC module can be reduced.
