2. Description of the Related Art Generally, a duplexer dielectric filter is a single antenna.
tenna) to provide simultaneous reception and transmission. Such a duplexer filter includes a receiving end filter and a transmitting end filter. The receiving end filter has a pass characteristic with respect to a receiving frequency and has a blocking characteristic with respect to a transmitting frequency, while the transmitting end filter has a transmitting frequency. Are configured to have a pass characteristic with respect to the reception frequency and a rejection characteristic with respect to the reception frequency. In order for a duplexer filter that satisfies such characteristics to be applicable to currently used mobile communication devices, miniaturization is premised. However, a filter that satisfies such requirements best is a duplexer dielectric. Filter.

FIG. 6 is a perspective view showing such a conventional integrated duplexer dielectric filter.

As shown in FIG. 6, a conventional duplexer dielectric filter is composed of a dielectric block including a reception filtering area and a transmission filtering area. The dielectric block 10 includes a first surface 11 and a second surface 13 facing each other, and a side surface 12 between the first surface 11 and the second surface 13. Is coated with a conductive material. Further, inside the dielectric block 10, a plurality of resonance holes 30a to 30g penetrating through the first surface 11 and the second surface 13 are arranged at regular intervals in a substantially parallel manner. Each of the plurality of resonance holes 30a to 30g has an inner surface coated with a conductive material, and thus forms a resonator.

[0005] Conductive patterns 31a to 31g of a predetermined size are arranged on the first surface 11 of the dielectric block 10. Each of the conductor patterns 31a to 31g has a corresponding one of the resonance holes 30a to 30g.
Each of the resonators is electrically coupled to a conductive material coated on the inside of the resonator to load a load capacitance inside each resonator.
e) is added to form a coupling capacitance between adjacent resonators. Multiple resonance holes 3
The resonance frequency of the resonator is determined by the added load capacitance of 0a to 30g, and the two resonators are coupled by forming the coupling capacitance. Further, input / output terminals 21 and 21 made of a conductor pattern are provided on both side surfaces of the first surface 11.
An antenna terminal 22 made of a conductor pattern is formed between the reception area and the transmission area of the dielectric block 10.

In general, in a duplexer dielectric filter, a high frequency band in a transmission region is relatively lower than a high frequency band in a receiving end. Therefore, while an electric field effect prevails between the resonance holes in the reception area, a magnetic field effect prevails between the resonance holes in the transmission area. Therefore, the resonance holes in the reception area form a capacitance coupling, and the resonance holes in the transmission area form an inductance coupling.
g).

In the duplexer dielectric filter having the above structure, the determination of the resonance frequency and the coupling between the resonators are performed by the plurality of conductor patterns 31 a to 31 formed on the first surface 11.
It depends on the size of g. That is, the characteristics of the duplexer dielectric filter include the conductor patterns 31a to 31g and the side 1.
2 and the conductive patterns 31a-3
Depends on the interval between 1g.

However, in order to form a compact and lightweight filter duplexer dielectric filter, it is necessary to reduce the thickness of the dielectric block 10 and narrow the interval between the resonance holes 30a to 30g. However, in a miniaturized filter, since the size of the first surface is reduced,
The distance between the conductor patterns 31a to 31g and the conductive material on the side surface 12 of the dielectric block 10 and the adjacent conductor pattern 3
There is a problem in that it is extremely difficult to obtain desired attenuation characteristics because there is a limit to the reduction of the interval between 1a to 31g.

Further, when the size of the dielectric block 10 is designed to be small, even when the distance between the conductive material on the side surface 12 and the conductive patterns 31a to 31g and between the conductive patterns 31a to 31g is reduced, the conductive patterns 31a ~ 3
An error occurred due to the limit of the 1 g printing process, and the volume of the dielectric block 10 could not be reduced beyond a certain limit.

Further, when the resonance frequency is adjusted by changing the shape of the conductor patterns 31a to 31g, both the coupling capacitance and the load capacitance change, so that the passing characteristics and blocking characteristics of the frequency signal change irregularly. There was the difficulty of interlocking. In addition, since it is difficult to automate the operation of adjusting the resonance frequency, labor costs are increased in the production process, and the cost competitiveness is reduced.

It is composed of In the dielectric block 100, a plurality of resonance holes 130a to 130 penetrating from the first surface 111 to the second surface 113 in a substantially parallel state at a predetermined interval from each other.
g is formed. A conductive material is applied or coated on a side surface 112 between the second surface 113 and the first surface 111 and the second surface 113 to form a ground electrode. The inner surfaces of the plurality of resonance holes 130a to 130g are coated or coated with a conductive material, and each resonance hole forms a resonator. Further, an open area is formed on the first surface 111 of the dielectric block, where the conductive material is not applied or coated.

Resonant holes 130a to 130g in first surface 111
Are formed in a predetermined size around the resonance holes 130a-1

Accordingly, the meaning of the input / output terminal and the antenna terminal in the detailed description of the present invention and the claims includes the input / output pad and the antenna pad of a general duplexer dielectric filter.

A duplexer dielectric filter generally consists of two filtering regions. When the first filtering area filters a signal received through the antenna terminal, the second filtering area filters a signal transmitted through the antenna terminal. Normally, it is not necessary to specially divide the filtering area in the dielectric block into a reception area and a transmission area.
Even in the case of a duplexer dielectric filter having the same structure, the receiving area and the transmitting area can be changed depending on a specific product. Therefore, in this embodiment, the reception area and the transmission area are specified and described for convenience of description, but such specification does not limit the technical idea of the present invention.

In the dielectric filter shown in the drawings,

Along the line, at least one second conductor pattern 140 having a strip line shape is arranged.

Resonance holes 130d to 130g along the arrangement direction of
It may be arranged on the upper part of g or on both sides of the upper and lower parts. The arrangement position of the second conductor pattern 140 has no influence on the magnitude of the coupling capacitance and the mutual coupling capacitance formed between adjacent resonators and between non-adjacent resonators. By arranging the second conductor pattern 140 above and below the resonance holes 130d to 130g, a larger coupling capacitance is formed, and the first conductor pattern 1
The size of 31d to 131g can be further reduced.

The strip-shaped second conductor pattern 140
Is formed from a fixed length and width, and as the length and width increase, the degree of coupling capacitance increases. Generally, the second conductor 140 can be connected to the ground electrode on the side surface 112 of the dielectric block 110, but is preferably short-circuited.

Resonant hole 130d in reception filtering area
At least one third conductive pattern 141 extending from the ground electrode of the dielectric block 110 toward the resonance holes 130d to 130g is formed on the upper portion of the third conductive pattern 141. The conductor pattern 141 is a resonance frequency adjusting conductor pattern in which the resonance frequency of the resonator changes depending on its length and width. Such a resonance frequency adjusting conductor pattern 14
1 may be formed integrally with the second conductor pattern 140 formed below the resonance holes 130d to 130g as shown in the drawing, and may extend toward the resonance holes 130d to 130g. Such a third conductor pattern 141 for the resonance frequency is
Independently of the conductor pattern, it can be formed independently on the upper or lower part of the resonance holes 130d to 130g.

The third conductor pattern 141 formed above the resonance holes 130d to 130g is connected to the ground electrode on the side surface 112 of the dielectric block 110 and is connected to the resonance holes 130d to 130g.
It is extended toward 0 g, but may be short-circuited with the ground electrode. Further, the third conductor pattern is the second conductor pattern 14.
Although it may be formed on one side in the length direction of 0, it may be formed on both sides. Such various shapes of the third conductor pattern 141 are all for adjusting the resonance frequency of the resonator, and it is not necessary to specify the arrangement position.

The ends of the transmitting / receiving terminals 121 and 123 and the antenna terminal 122 have length adjusting regions 121a and 121a, respectively.
2a and 123a are formed. Length adjustment area 121

The degree of electromagnetic coupling with the resonance holes 130a to 130g is controlled by adjusting the length of the antenna terminals 122a, 123a and the antenna terminal 122.

Resonant hole 130a in transmission filtering area
To 130c, a strip-shaped fourth conductor 135a
To 135d are formed. Fourth conductor pattern 135
a to 135d are separated from the first conductor patterns 131a to 131c by a certain distance, and are adjacent to the resonance holes 130.
Two each are formed between a and 130b and between 130b and 130c, and are connected to the ground electrode on the side surface 112 of the dielectric block 110. Fourth conductor pattern 135a
135d suppresses the capacitance between the resonance holes 130a to 130c, forms a coupling inductance, and forms an attenuation pole at a frequency higher than the pass band of the dielectric filter. Accordingly, the fourth conductor patterns 135a to 135a
A length adjustment region 147 is formed at the end of 5d, and the frequency at which the attenuation pole is formed can be adjusted by adjusting the length of the fourth conductor patterns 135a to 135d. At this time, the length adjustment region 147 is formed at opposite ends of two adjacent fourth conductor patterns between the resonance holes. That is, if the length adjustment region of one conductor pattern is formed above the first surface, the length region of the other adjacent conductor pattern is formed below the first surface.

Further, the resonance hole 1 in the transmission filtering area
A fifth pattern 145 for adjusting the resonance frequency of the resonator extending from the ground electrode on the side surface 112 of the dielectric block 110 toward the resonance holes 130a to 130c is formed on the upper portions 30a to 130c similarly to the reception filtering area. . Also at this time, the fifth conductor pattern 145 is
Can be short-circuited to the ground electrode of the
It may be formed at the upper and lower portions of Oa to 130c.

The operation and effect of the present invention according to the above configuration will be described below.

First, as shown in FIG.
2. The transmission filtering area on the left side serves as a transmission filter for transmitting high frequency to the outside, and the reception filtering area on the right side of the antenna terminal 122 serves as a reception filter for receiving high frequency from the outside. At this time, the plurality of resonance holes 130a to 13013 formed in a positional relationship parallel to each other in the transmission filtering area and the reception filtering area.
Each of 0 g functions as a quarter-wavelength resonator while maintaining a predetermined interval from each other.

FIG. 2 is an equivalent circuit diagram of a transmission filtering region of the duplexer dielectric filter according to the present invention, wherein the filtering characteristic is a load capacitance (C1,
C2 and C3) can be realized. Due to the presence of the load capacitance, the resonance point can be set at a frequency lower than the resonance frequency of each of the resonators r1 to r3. This means that the length of the resonator is shorter than a quarter wavelength (λ) of the resonance point, but in this case, due to an electric field existing between the resonators. Since the coupling is suppressed, a magnetic field (magnetic f
ield) is dominant.

As a result, inductive couplings M1 and M2 are formed between the resonators.

On the other hand, for frequencies higher than the pass band, the length of the quarter wavelength is shortened, so that the effect of magnetic field coupling, which has been dominant as a whole, is reduced, and the frequency reaches a specific frequency. If the coupling effect disappears (transmission-zero), an attenuation pole is formed. According to such a principle, the attenuation pole formed on the high frequency side of the transmission end pass band is adjusted by appropriately adjusting the load capacitance.

Therefore, in the duplexer dielectric filter of the present invention, the length of the fourth patterns 135a to 135d and the length of the fifth conductor pattern 145 are adjusted when adjusting the load capacitance for adjusting the characteristics of the filter in the design or production process. Will do. At this time, the fourth conductor patterns 135a to 135a are provided between the resonance holes.
When only one d is formed, the load capacitance can be adjusted according to the change in the length of the electrode, but at the same time, the coupling capacitance between the resonance holes changes. This increases the difficulty of tuning the resonance frequency.

Therefore, as in the present invention, the fourth conductor patterns 135a to 135d are formed in a pair or more, and the arrangement of the length adjustment regions 147 is selected in the direction in which the ground electrodes cross each other. Since the variable caused by the capacitance coupling can be reduced, the procedure for adjusting the resonance frequency is simplified, thereby increasing the efficiency of the frequency adjustment operation.

On the other hand, in the integrated dielectric duplexer of the present invention, the structure of the reception filtering area is the resonance hole 13.
0d to 130g and the second conductor pattern 1 formed therearound
However, since the pass band frequency of the reception area is higher than the pass band frequency of the transmission area, the load capacitance should be reduced accordingly. Furthermore, the receiving area must have a stopband for low frequencies in the passband, as opposed to the transmitting area. At this time, if the frequency is reduced, the length of the quarter wavelength is increased, and the coupling by the magnetic field is increased as a whole between the resonance holes 130d to 130g. Therefore, in order to cancel the coupling effect at a low frequency and create an attenuation pole, the coupling capacitance (coupling) is higher than that in the transmission region.
ling capacitance) should be increased. FIG. 3 shows an equivalent circuit diagram. FIG. 3 is an equivalent circuit diagram of the receiving region of the integrated dielectric duplexer of the present invention. When the coupling capacitance between the resonators r4 and r7 increases, the electric field coupling between the resonators becomes dominant.

In the receiving area according to the present invention, a second portion formed below the resonance holes 130d to 130g so as not to be connected to the ground electrode on the side surface 112 of the dielectric block 110.
Depending on the conductor pattern 140, the resonance holes 130a-130
g acts to suppress the load capacitance and increase the coupling capacitance between adjacent and non-adjacent resonant holes. Further, the operation of adjusting the resonance frequency can be easily performed by the third conductor pattern 141 in the reception filter area.

FIG. 4 is a frequency characteristic graph of the transmission region of the integrated dielectric duplexer according to the present invention, and FIG. 5 is a frequency characteristic graph of the reception region of the integrated dielectric duplexer according to the present invention. As shown in FIGS. 4 and 5, in the transmission region of the integrated dielectric duplexer according to the present invention, a high attenuation ratio can be obtained in a high frequency region in the pass band, and in the reception region, a high attenuation ratio can be obtained. A high attenuation ratio can be obtained in a low frequency region.
It is the fourth conductor pattern 13 in each transmission area.
It is possible by adjusting the length of 5a to 135d and the fifth conductor pattern 145, and in the reception area, by adjusting the length of the second conductor pattern 140 and the third conductor pattern 141.

The integrated dielectric duplexer according to the present invention is not limited to the above-described configuration, and can be variously modified and implemented within the range permitted by the technical idea of the present invention.

[0040]

As described above, in the integrated dielectric duplexer according to the present invention, the load capacitance and the coupling capacitance with respect to the resonance hole are respectively changed by changing the length of a predetermined portion of an electrode formed from a predetermined conductor pattern. Therefore, the adjustment of the load capacitance and the coupling capacitance can be separately performed without interlocking, so that the adjustment of the frequency band and the resonance frequency can be easily performed. .

Further, the resonance frequency adjustment operation is simplified by the integrated dielectric duplexer according to the present invention, thereby improving the productivity of the product and increasing the price competitiveness through cost reduction in the design and manufacturing processes. Can be provided.
