The second conductor 42 and the metal patch 30 are conductive. The second conductor 42 and the metal patch 30 include, for example, a metal. The second conductor 42 and the metal patch 30 may include copper.

The second conductor 42 is multiply provided in the second direction and the third direction.

As illustrated in FIG. 4, for example, the second conductors 42 are provided to be proximal to one of the third to sixth surfaces S3 to S6.

The metal patch 30 is multiply provided on the first surface S1. The metal patches 30 are arranged in the second direction and the third direction. For example, the metal patches 30 are included in an EBG (Electromagnetic Band Gap). The metal patches 30 are provided to be separated from the second conductors 42 in the second direction and the third direction. For example, at least one of the multiple metal patches 30 and at least one of the multiple second conductors 42 are arranged in the second direction or the third direction.

As illustrated in FIG. 5, a first conductor 41 is provided Inside the first plate portion 11. For example, the first conductor 41 extends in the first direction. The second conductor 42 is electrically connected to the first conductor 41. The first conductors 41 are provided at positions respectively overlapping the second conductors 42 in FIG. 4. In other words, the first conductors 41 are multiply provided. A portion of the first conductors 41 is arranged in the second direction; and another portion of the first conductors 41 is arranged in the third direction. For example, the second conductors 42 are set to a fixed potential via the first conductors 41.

The first conductors 41 are provided between the third conductor 43 and the second conductors 42.

A via 31 is provided inside the first plate portion 11. The via 31 is connected to the metal patch 30. The via 31 is further connected to the third conductor 43. Therefore, the second conductor 42 and the metal patch 30 are electrically connected. In other words, the potential of the second conductor 42 is equal to the potential of the metal patch 30.

The first conductor 41, the third conductor 43, and the via 31 are conductive. The first conductor 41, the third conductor 43, and the via 31 include, for example, a metal. The first conductor 41, the third conductor 43, and the via 31 may include copper.

In FIG. 6 and FIG. 7, an enlargement of only one second conductor 42 of the multiple second conductors 42 provided at the third plate portion 13 vicinity is illustrated. In FIG. 6 and FIG. 7, the portion of the second conductor 42 overlapping the first conductor 41 in the first direction is Illustrated by a broken line. The second conductor 42 illustrated in FIG. 7 is the same as the second conductor 42 of the multiple second conductors 42 illustrated in FIG. 6.

The second conductor 42 includes a first region 42a and a second region 42b. An end of the first region 42a is connected to the first conductor 41. The position in the second direction of at least a portion of the first region 42a is between the position in the second direction of the end of the first region 42a and the position in the second direction of at least a portion of the third plate portion 13.

An end of the second region 42b is connected to the first conductor 41. The position in the second direction of at least a portion of the second region 42b is between the position in the second direction of the end of the second region 42b and the position in the second direction of at least a portion of the third plate portion 13.

The distance in the second direction between the first region 42a and the third plate portion 13 is not more than the length in the third direction of at least a portion of the first region 42a. As an example, a distance D1 between the third plate portion 13 and the end portion in the second direction of the first region 42a is shorter than a length L1 in the third direction of a portion of the first region 42a. It is more desirable for the end portion in the second direction of the first region 42a to contact the third surface S3. In other words, it is desirable for the distance D1 to be zero.

Similarly, the distance in the second direction between the second region 42b and the third plate portion 13 also is not more than the length in the third direction of at least a portion of the second region 42b. As an example, a distance D2 between the third plate portion 13 and the end portion in the second direction of the second region 42b is shorter than a length L2 in the third direction of a portion of the second region 42b. It is more desirable for the end portion in the second direction of the second region 42b to contact the third surface S3. In other words, it is desirable for the distance D2 to be zero.

An opening SP is provided between at least a portion of the first region 42a and at least a portion of the second region 42b. In other words, at least a portion of the second region 42b is separated from at least a portion of the first region 42a in the third direction.

The length in the third direction of at least a portion of the first region 42a is not more than the length in the third direction of at least a portion of the opening SP. As an example, the length L1 in the third direction of a portion of the first region 42a is not more than a length L3 in the third direction of a portion of the opening SP.

The length in the third direction of at least a portion of the second region 42b is not more than the length in the third direction of the at least a portion of the opening SP. As an example, the length L2 in the third direction of a portion of the second region 42b is not more than the length L3 in the third direction of the portion of the opening SP.

The length in the first direction of the first conductor 41 is designed so that the first conductor 41 has an antiresonant frequency in a desired cut-off band. It is desirable for the length L1 and the length L2 to be within ±20% of the diameter of the first conductor 41 so that the second conductor 42 similarly has an antiresonant frequency in a desired cut-off band. The diameter of the first conductor 41 is the length in the second direction of the first conductor 41 or the length in the third direction of the first conductor 41.

The first region 42a may include a bent portion. As an example, the first region 42a includes the multiple bent portions of a first bent portion CP1, a second bent portion CP2, and a third bent portion CP3 as illustrated in FIG. 6.

Similarly, the second region 42b also may include a bent portion. As an example, the second region 42b includes the multiple bent portions of a fourth bent portion CP4, a fifth bent portion CP5, and a sixth bent portion CP6 as illustrated in FIG. 6.

As illustrated in FIG. 7, the first region 42a includes, for example, a first portion P1 and a third portion P3. The second region 42b includes, for example, a second portion P2 and a fourth portion P4. The first to fourth portions P1 to P4 are aligned with the second direction.

A distance D4 in the third direction between the third portion P3 and the fourth portion P4 is longer than a distance D3 In the third direction between the first portion P1 and the second portion P2. The distance D3 and the distance D4 are longer than the distance D1 and the distance D2.

FIG. 8 illustrates the appearance of the first conductor 41 and the second conductor 42 in perspective from the bottom surface. In FIG. 8, the first plate portion 11 is illustrated as being transparent.

For example, a length L5 in the first direction of the first conductor 41 is equal to a length L6 from one end to the other end of the first region 42a and equal to a length L7 from one end to the other end of the second region 42b illustrated in FIG. 7. The length L6 may be the average of the lengths of the two sides of the first region 42a from the one end of the first region 42a toward the other end of the first region 42a.

In other words, in the example illustrated in FIG. 7, the length L6 may be the average of a length L6a and a length L6b. Similarly, the length L7 may be the average of the lengths of the two sides of the second region 42b from one end of the second region 42b toward the other end of the second region 42b. In other words, the length L7 may be the average of a length L7a and a length L7b.

Although the length L6 is equal to the length L7 In the example illustrated in FIG. 7, the length L6 may be different from the length L7. In the example illustrated in FIG. 6 and FIG. 7, the second conductor 42 passes through the first conductor 41 and has a structure that is symmetric with respect to a virtual plane including the second direction; but the second conductor 42 may have a structure that is asymmetric with respect to the virtual plane.

Thus, a portion of the second conductors 42 of the multiple second conductors 42 provided at the third plate portion 13 vicinity is described using FIG. 6 to FIG. 8. A configuration that is similar to the configuration illustrated in FIG. 6 to FIG. 8 is employable for the second conductors 42 provided at the vicinities of the fourth to sixth plate portions 14 to 16 as well.

According to the embodiment, because the electronic device 1 includes the first conductor 41 and the second conductor 42, it is possible to reduce the noise generated in the housing 10 interior.

To further reduce the noise generated in the housing 10 interior, it is desirable for the distance D1 to be the length L1 or less and for the distance D2 to be the length L2 or less. More favorably, the distance D1 and the distance D2 are zero. Further, it is desirable for the length L1 and the length L2 to be the length L3 or less.

For example, the length L6 and the length L7 are designed according to the frequency of the electromagnetic wave at which the reduction is desirable. Because the first region 42a and the second region 42b include bent portions, it is possible to lengthen the length L6 and the length L7 while suppressing the increase of the surface area occupied by the second conductor 42 on the first surface S1.

Because the second conductor 42 is multiply provided in the second direction and the third direction, it is possible to even further reduce the noise generated in the housing 10 interior.

In a housing that includes a resin sealing a system circuit board and in a housing that includes a metal, spatial noise that is caused by reflections of electromagnetic waves may occur between the interior wall surfaces, the ceiling, and the circuit board in the housing interior. Hotspots which are regions where the intensity of the noise is high may occur due to the spatial noise; and oscillations of the circuit provided in the housing interior and/or resonance of the housing may occur. As a countermeasure, it may be considered to widely use filter components; but in such a case, it is difficult to downsize the system board. As another countermeasure, it may be considered to increase the length of the path of the reflected waves; but in such a case, it is difficult to reduce the height of the housing.

A system may be considered that includes several layer structures into which the system functions from SOC to the printed circuit board are subdivided. Then, each layer is placed in a housing to suppress the noise caused by the circuit operation and the corrosion due to the external air. Such housings may be roughly divided into housings made of resin and housings made of metal. It may be considered to place circuits in which noise is generated easily due to the circuit operation and circuits in which misoperations occur easily due to noise of the external environment in a housing made of a metal.

The noise may be roughly divided into noise that Is coupled by the lead-lead capacitance on the circuit board, and noise that propagates through space. The noise of the former can be reduced by reducing the capacitive coupling between the leads. Therefore, the noise of the former can be suppressed by providing a filter circuit and by widening the lead spacing. On the other hand, the noise of the latter that propagates through space may not be affected at all according to the location where the filter is provided. Further, because hotspots occur due to reflections of the housing, a countermeasure is performed in which a material that suppresses the reflections or absorbs the electromagnetic waves is adhered to the side wall inside the housing. However, in such a case, because the dielectric constant of the adhered material is added to the dielectric constant of the original circuit design, the circuit operation shifts greatly from the original design; and there is a risk that operation errors may occur.

The electronic device 1 according to the embodiment is useful for these problems.

The length L6 and the length L7 are, for example, an odd multiple of ½ of the wavelength or an odd multiple of ¼ of the wavelength determined using the dielectric constant of the environment (the air, the substrate, etc.) contacting the metal based on the frequency propagating through the metal included in the housing. As an example, ¼ of the wavelength is 2.5 mm, and ½ of the wavelength is 5 mm in the case where a frequency in the vicinity of 14.5 GHz used in satellite communication is input to the electronic device 1, the main unit 10a includes a metal such as copper, aluminum, gold, etc., the lid 10b includes a metal such as copper, aluminum, gold, etc., and the dielectric constant of the environment contacting the metal is 4.2. Accordingly, the length L6 and the length L7 may be an odd multiple of ½ or an odd multiple of ¼ of the wavelength. In such a case, if the difference between the length L6 and the odd multiple of ½ of the wavelength or the odd multiple of ¼ of the wavelength is ±20%, these values can be considered to be substantially equal. Similarly, if the difference between the length L7 and the odd multiple of ½ of the wavelength or the odd multiple of ¼ of the wavelength is ±20%, these values can be considered to be substantially equal.

Simulation results relating to the electronic device 1 will now be described with reference to FIG. 9. FIG. 9 is a graph illustrating characteristics of electronic devices according to the first embodiment and a comparative example. In FIG. 9, the horizontal axis illustrates the frequency; and the vertical axis illustrates the pass characteristic of a signal using S-parameters of the frequencies. The broken line in FIG. 9 illustrates the characteristic of the electronic device according to the comparative example that does not include the first conductor 41 and the second conductor 42. The solid line illustrates the characteristic of the electronic device 1.

In the simulation illustrated in FIG. 9, the dielectric constant of the main unit 10a is set to 2.2; and the dielectric constant of the lid 10b is set to 4.1. The length L5, the length L6, and the length L7 are set to 2.4 mm. From FIG. 9, it can be seen that the noise of all frequencies from 13.6 to 15.5 GHz are reduced. In particular, it can be seen that the noise can be greatly reduced for the frequencies from 14.0 to 14.5 GHz which is the desired cut-off frequency band in the case where the electronic device 1 is used in a satellite communication application.

Second Embodiment

FIG. 10 is an enlarged plan view of a portion of an electronic device 2 according to a second embodiment.

Similarly to the first embodiment, the distance D1 is, for example, shorter than the length L1. The distance D2 is, for example, shorter than the length L2. The distance D1 and the distance D2 are shorter than the distance D3 in the second direction between the first portion P1 and the second portion P2. In the embodiment, the distance D3 is, for example, the distance in the third direction between the other end of the first region 42a and the other end of the second region 42b.

In the example illustrated in FIG. 10, a length L8 in the second direction of the second conductor 42 is longer than a length L9 In the third direction of the second conductor 42. However, the length L9 may be equal to the length L8; and the length L9 may be longer than the length L8.

For example, the distance D1 in the second direction between the third surface S3 and the other end of the first region 42a is shorter than the length L1 in the second direction of the other end of the first region 42a. For example, the distance D1 in the second direction between the third surface S3 and the other end of the second region 42b is shorter than the length L2 in the second direction of the other end of the second region 42b.

In the example Illustrated in FIG. 11, the length L8 in the second direction of the second conductor 42 is equal to the length L9 in the third direction of the second conductor 42. However, the length L9 may be longer than the length L8; and the length L8 may be longer than the length L9.
