However, the present invention is not restricted to the first and second preferred embodiments and can variously be modified according to the structure and coupling manner of the inputoutput coupling circuits.
FIGS. 10A and 10B are a schematic plan view and a partially cut-away front sectional view for illustrating a method for adjusting the frequency of an attenuation pole of a dual-mode band pass filter according to a third preferred embodiment of the present invention.
In a dual-mode band pass filter 21, a metal film 3 is embedded in a dielectric substrate 22. On an upper surface 22a of the dielectric substrate 22, inputoutput coupling circuits 25 and 26 are provided. Coupling portions 25a and 26a of the inputoutput coupling circuits 25 and 26 are arranged in such a manner that the portions 25a and 26a overlap with the metal film 3 via a dielectric substrate layer. In other words, in the first preferred embodiment, the inputoutput coupling circuits are flush with the metal film 3 and the coupling portions 5a and 6a are capacitively coupled to the metal film 3. However, as shown in FIGS. 10A and 10B, the inputoutput coupling circuits 25 and 26 may be located at positions that are different from that of the metal film 3. In this case, the dielectric substrate 22 has a multilayer structure that is formed by stacking a plurality of dielectric layers, and the coupling portions 25a and 26a are capacitively coupled to the metal film 3 via the dielectric-substrate layer.
In the third preferred embodiment of the present invention, by changing the coupling points of the inputoutput coupling circuits 25 and 26 and the metal film 3, as shown in the case of the first preferred embodiment, the attenuation-pole frequency can be changed.
In the first preferred embodiment, the coupling portions 5a and 6a are fixed and the positions of the inputoutput portions 5b and 6b are deviated. Alternatively, by moving the positions of the coupling portions 5a and 6a along the sidelines 3b and 3c, the frequency of the attenuation pole can be adjusted. In addition, both of the above two ways of adjusting may be used together. Similarly, in the third preferred embodiment, the frequency of the attenuation pole can be adjusted by changing the positions of the coupling portions 25a and 26a of the inputoutput coupling circuits 25 and 26 andor by deviating positions at which the inputoutput portions 25b and 26b are coupled to the coupling portions 25a and 26a.
Furthermore, as shown in the third preferred embodiment, in a dual-mode band pass filter capable of using the method of the present invention, the metal film may be embedded in the dielectric substrate. In addition, regarding the inputoutput coupling circuits, it is not necessary to form the circuits on the upper surface of the dielectric substrate. The inputoutput coupling circuits may be formed in the dielectric substrate. Additionally, it is not necessary to form the ground electrode 4, as shown in the first preferred embodiment, on the lower surface of the dielectric substrate. The ground electrode 4 may be formed in the dielectric substrate.

In this preferred embodiment, a metal film 3 is embedded in a dielectric substrate 2, and inputoutput coupling circuits 35 and 36 defined by inductance coils are disposed on the dielectric substrate 2. The inputoutput coupling circuits 35 and 36 are directly and electrically connected to the metal film 3 via the via-hole electrodes 35a and 36a.
In other words, in the second preferred embodiment, the strip lines 15 and 16 as the inputoutput coupling circuits are connected to the metal film 3 such that the strip lines 15 and 16 are flush with the metal film 3. However, as shown in the fourth preferred embodiment of the present invention, the inputoutput coupling circuits 35 and 36 may be positioned at a height that is different from the height at which the metal film 3 is positioned. In the fourth preferred embodiment of the present invention, as in the case of the second preferred embodiment, the frequency of the attenuation pole can be changed by changing the positions of the via-hole electrodes 35a and 36a, that is, by changing the positions of points at which the inputoutput coupling circuits 35 and 36 are coupled to the metal film 3. In addition, the inputoutput coupling circuits may be embedded in the substrate.

In each of the first to fourth preferred embodiments,
As described above, according to the first to fourth preferred embodiments of the present invention, the metal film for forming a resonator is disposed on the dielectric substrate, and at least one opening is formed in the metal film to couple two resonance modes. Thus, the positions of the points at which the inputoutput coupling circuits are coupled to the metal film are not specifically restricted. As a result, by coupling the two resonance modes, band characteristics required as a dual-mode band pass filter can be obtained.
In the first preferred embodiment of the present invention, the inputoutput coupling circuits include the coupling portions, which are capacitively coupled to the metal film, and the inputoutput portions. Since at least either the coupling portions or the inputoutput portions are moved in a direction along the perimeter of the metal film facing via the gap, the frequency of the attenuation pole can be easily adjusted.
In the method according to the second preferred embodiment of the invention, the inputoutput coupling circuits are preferably defined by inductors. One end of each of the inputoutput coupling circuits is directly and electrically connected to the metal film, and the points at which the inputoutput coupling circuits are coupled to the metal film are moved along the perimeter of the metal film. With this arrangement, the frequency of the attenuation pole of the dual-mode band pass filter can be easily adjusted.
In the third preferred embodiment of the present invention, a dielectric multilayer structure between the metal film and the inputoutput coupling circuits. The inputoutput coupling circuits overlap with the metal film via the dielectric multilayer structure to be capacitively coupled to the metal film. In this arrangement, the frequency of an attenuation pole of the dual-mode band pass filter can easily be adjusted by moving the positions of the inputoutput coupling circuits along the perimeter of the metal film on the dielectric multilayer structure.
In the fourth preferred embodiment of the present invention, the insulating layer having via-hole electrodes is disposed between the inputoutput coupling circuits and the metal film. First side ends of the via-hole electrodes are electrically connected to the inputoutput coupling circuits, and the other ends thereof are electrically connected to the metal film. Thus, the frequency of the attenuation pole of the dual-mode band pass filter can easily be adjusted by moving the positions connecting the via-hole electrodes to the inputoutput coupling circuits and the metal film.
