<1. Overview>
First, in order to make the characteristics of the antenna element according to an embodiment of the present disclosure easier to understand, an example of a schematic configuration of an information processing apparatus to which the antenna element can be applied will be described, and then, according to the embodiment Organize the issues of antenna elements.

For example, FIG. 1 is an explanatory diagram for explaining an example of a schematic configuration of an information processing apparatus to which the antenna element according to the present embodiment can be applied. The information processing apparatus 1 is configured as a so-called wearable device. More specifically, as shown in FIG. 1, the information processing apparatus 1 has a ring shape with a part opened (in other words, a headband shape or a U-shape). At least a part of the inner surface of the part is attached to the user so as to abut on a part of the user's neck (that is, to hang around the neck).

The information processing apparatus 1 includes, for example, a sound output unit such as a so-called speaker or the like in a portion located in the vicinity of the user's ear when worn by the user, and receives sound information such as sound from the sound output unit. By outputting, the acoustic information is presented to the user. In addition, the information processing apparatus 1 includes, for example, a sound collection unit such as a so-called microphone in a portion located in the vicinity of the user's mouth when worn by the user, and the sound emitted by the user from the sound collection unit. Collect sound as acoustic information.

Further, the information processing apparatus 1 includes an antenna element 10 for communicating with another external device via a wireless communication path inside the casing. For example, in the example shown in FIG. 1, when the information processing apparatus 1 is attached to the user's neck, the antenna element 10 is connected to the user's neck from the vicinity of the user's back of the casing of the information processing apparatus 1. It is incorporated in at least a part of the portion extending forward along the side surface.

Here, with reference to FIG. 2, a mounting example in the case where the antenna element 10 is built in the housing of the information processing apparatus 1 shown in FIG. FIG. 2 is an explanatory diagram for explaining a mounting example of the antenna element 10 according to the present embodiment. In the example shown in FIG. 2, the horizontal direction of the drawing may be described as the x direction and the vertical direction of the drawing may be described as the y direction. Further, when the left and right are particularly distinguished from each other in the horizontal direction (that is, the x direction) in the drawing, the right direction may be described as the + x direction and the left direction may be described as the −x direction. Similarly, in the vertical direction (ie, the y direction) in the drawing, when the upper and lower sides are particularly distinguished, the upper direction may be described as the + y direction and the lower direction may be described as the -y direction.

2, the long member indicated by reference numeral 20 corresponds to a ground plate on which various components of the information processing apparatus 1 are mounted. The ground plane 20 is bent into a ring shape with a part opened (in other words, a headband shape or a U-shape) and is built in the housing of the information processing apparatus 1. The antenna element 10 is provided on at least a part of the ground plane 20. The ground plane 20 is formed of, for example, a good conductor such as low resistance Au, Ag, or Cu, or a thin conductor plate made of Cu or phosphor bronze, and serves as a ground for the antenna element 10. For example, in the example illustrated in FIG. 2, the ground plane 20 has a width of 410 [mm] in the x direction and 20 [mm] in the y direction.

The antenna element 10 is formed of a good conductor such as low resistance Au, Ag, or Cu, or a conductor thin plate made of Cu or phosphor bronze, by a technique such as etching, with respect to the ground plane 20. The antenna element 10 needs to be formed so as to be within a range of 410 [mm] in the x direction and 20 [mm] in the y direction in order to be built in the housing of the information processing apparatus 1. Therefore, in the example shown in FIG. 2, the antenna element 10 is formed to have a long shape in the x direction.

Here, in order to make the characteristics of the antenna element 10 according to the present embodiment easier to understand, a case where a so-called inverted F type monopole antenna is provided on the ground plane 20 shown in FIG. 2 will be described as a comparative example. Thus, the problems of the antenna element 10 according to this embodiment will be summarized. For example, FIG. 3 is an explanatory diagram for explaining an example of the configuration of the antenna element 90 according to the comparative example. In the example shown in FIG. 3, the horizontal direction of the drawing corresponds to the x direction shown in FIG. 2, and the vertical direction of the drawing corresponds to the y direction shown in FIG.

As shown in FIG. 3, the antenna element 90 according to the comparative example is configured as a so-called monopole antenna having a long antenna element 91. As shown by reference numeral 94, the antenna element 91 is electrically connected to the ground plane 20 at one end in the longitudinal direction. The antenna element 91 is bent at least partially to the ground plane 20. They are provided so as to be substantially parallel (that is, extending in the −x direction). Of the antenna element 91, a portion indicated by reference numeral 94 and electrically connected to the ground plane 20 may be referred to as a “short-circuit end”. In addition, a feeding point 93 is provided in the vicinity of the end portion on the side where the short-circuit end 94 is provided in the end portion in the x direction of the antenna element 91. At the feeding point 93, at least a part of the antenna element 91 is provided in the vicinity of the ground plane 20 so as to be separated from the ground plane 20. The length of the antenna element 91 is such that resonance occurs at the operating frequency.

Here, a current flows through the antenna element 91 due to the high-frequency power supplied from the feeding point 94. At this time, the composition of the current flowing from the feed point 94 toward the end of the antenna element 91 opposite to the feed point 94 and the configuration of the current reflected at the end is the current distribution in the antenna element 91. Become.

Here, it is assumed that a current flows in the direction indicated by the reference symbol A1 with respect to the antenna element 91. At this time, due to the current flowing in the antenna element 91 in the direction A1, the portion of the ground plane 20 parallel to the antenna element 91 in the x direction is induced in the direction A2 opposite to the direction A1. May occur. In this case, the current flowing in the direction A1 on the antenna element 91 side is canceled by the induced current flowing in the direction A2 on the ground plane 20 side (that is, the current in the reverse phase), and the sensitivity of the antenna element 90 is deteriorated. There is a case. At this time, the influence of the induced current flowing on the ground plane 20 side tends to become stronger as the width between the antenna element 91 and the ground plane 20 is narrower. Therefore, in the configuration like the antenna element 90 according to the comparative example, it is necessary to dispose the antenna element 91 as far as possible in the y direction with respect to the ground plane 20, and further reduce the thickness in the y direction ( That is, it is difficult to reduce the height.

Therefore, in the present disclosure, in view of the problems described above, an antenna element 10 that can be further reduced in height and an information processing apparatus 1 that uses the antenna element 10 are proposed. Hereinafter, the antenna element 10 according to the present embodiment will be described in more detail.

<2. Configuration of antenna element>
First, an example of the configuration of the antenna element 10 according to an embodiment of the present disclosure will be described with reference to FIG. FIG. 4 is an explanatory diagram for explaining an example of the configuration of the antenna element 10 according to the present embodiment, and corresponds to an enlarged view of the antenna element 10 shown in FIG. 2. In the example shown in FIG. 4, the horizontal direction of the drawing corresponds to the x direction shown in FIG. 2, and the vertical direction of the drawing corresponds to the y direction shown in FIG.

As shown in FIG. 4, the antenna element 10 includes an antenna element 11 and an antenna element 12.

The antenna element 11 includes elongated

conductor elements

111 and 113 that extend in the −x direction and are provided so as to be substantially parallel to each other. The

conductor elements

111 and 113 are arranged apart from each other in the y direction with respect to the end portion 201 on the y direction side of the ground plane 20 provided so as to extend in the x direction. In the description, it is assumed that the

conductor elements

111 and 113 are arranged so that the conductor element 113 is interposed between the ground plane 20 and the conductor element 111. At this time, each of the

conductor elements

111 and 113 and the end portion 201 of the ground plane 20 are substantially parallel to each other. The conductor element 111 corresponds to an example of a “first member”, and the conductor element 113 corresponds to an example of a “second member”. The base plate 20 corresponds to an example of a “third member”.

In the example shown in FIG. 4, the conductor element 111 has one end portion (for example, the end portion on the + x direction side) among the end portions in the extending direction that is electrically connected to the feeding point 13. The conductor element 111 has an end portion in the same direction as the one end portion of the end portions in the extending direction of the conductor element 113 (for example, the end portion on the −x direction side) of the other end portion (for example, the end portion on the −x direction side). That is, it is electrically connected to the vicinity of the end on the −x direction side. Further, as shown by reference numeral 14, the conductor element 113 has an end opposite to the end electrically connected to the conductor element 111 (that is, an end on the + x direction side) with respect to the ground plane 20. Are electrically connected (ie short-circuited). Hereinafter, a portion where the conductor element 113 and the ground plane 20 are short-circuited, which is indicated by reference numeral 14, may be referred to as a “short-circuit end”.

Also, the conductor element 111 protrudes in the vicinity of the end portion on the side electrically connected to the conductor element 113 in the −x direction (that is, the direction in which the

conductor elements

111 and 113 run in parallel). An open end 115 is provided. Similarly, the open end 115 of the conductor element 113 is provided in the vicinity of the end on the side electrically connected to the conductor element 111 so as to protrude in the −x direction.

The antenna element 12 is provided on the + x direction side with respect to the antenna element 11. The antenna element 12 includes elongated

conductor elements

121 and 123 that extend in the + x direction and are provided to be substantially parallel to each other. The

conductor elements

121 and 123 are arranged away from the end portion 201 of the ground plane 20 in the y direction. In the description, it is assumed that the

conductor elements

121 and 123 are arranged so that the conductor element 123 is interposed between the ground plane 20 and the conductor element 121. At this time, each of the

conductor elements

121 and 123 and the end portion 201 of the ground plane 20 are substantially parallel to each other. The conductor element 121 corresponds to an example of a “fourth member”, and the conductor element 123 corresponds to an example of a “fifth member”.

In the example shown in FIG. 4, among the end portions of the conductor element 121 in the extending direction, the vicinity of one end portion (for example, the end portion on the + x direction side) and the end portion of the conductor element 123 in the extending direction. The vicinity of the end in the same direction as the one end (that is, the end on the + x direction side) is electrically connected. Similarly, the vicinity of the other end of the conductor element 121 (ie, the end on the −x direction side) and the vicinity of the other end of the conductor element 123 (ie, the end on the −x direction side) are: Electrically connected. That is, the conductor element 121 and the conductor element 123 form a loop shape. In addition, the end portion side of the conductor element 123 on the −x direction side is electrically connected to the feeding point 13. The feeding point 13 indicates a portion of the antenna element 10 that is electrically connected to the feeding unit (or feeding line). With such a configuration, the end on the −x direction side of the conductor element 121 is electrically connected to the feeding point 13.

The conductor element 121 is provided with an open end 125 in the vicinity of the end portion on the side electrically connected to the conductor element 123 so as to protrude toward the + x direction. Similarly, the open end 125 of the conductor element 123 is provided in the vicinity of the end on the side electrically connected to the conductor element 121 so as to protrude in the + x direction. Further, the open end 125 of the conductor element 123 is also provided in the vicinity of the end on the −x direction side so as to protrude in the −x direction.

In the example shown in FIG. 4, the antenna element 10 includes the antenna element 11 and the antenna so that the end on the + x direction side of the conductor element 111 and the end on the −x direction side of the conductor element 121 are connected. The element 12 is integrally formed. With such a configuration, the end on the + x direction side of the conductor element 111 is electrically connected to the feeding point 13.

In the example shown in FIG. 4, the antenna element 11 and the antenna element 12 are configured to be able to transmit and receive radio waves in different frequency bands. Specifically, the antenna element 11 is configured to be able to transmit and receive a 2.4 GHz band radio wave in a frequency band used in a wireless LAN or the like. Therefore, the size of each part of the antenna element 11 is set so that the antenna element 11 resonates at a frequency (that is, an operating frequency) belonging to the 2.4 GHz band. Similarly, the antenna element 12 is configured to be able to transmit and receive 5 GHz band radio waves in a frequency band used in a wireless LAN or the like. Therefore, the size of each part of the antenna element 12 is set so that the antenna element 12 resonates at a frequency (that is, an operating frequency) belonging to the 5 GHz band.

For example, in the example shown in FIG. 4, the antenna element 10 is configured so that the width in the x direction including the open ends 115 and 125 is 42 [mm] and the width in the y direction is 2 [mm]. In the example shown in FIG. 4, the width of the antenna element 10 in the y direction is approximately 1/60 of the wavelength corresponding to the operating frequency of the antenna element 11 (that is, the frequency belonging to the 2.4 GHz band).

The width in the y direction of each of the

conductor elements

111 and 113 is 0.5 [mm], and the distance in the y direction between the conductor element 111 and the conductor element 113 is 0.5 [mm]. Moreover, the space | interval of the y direction between the conductor element 113 and the edge part 201 of the ground plane 20 will be 0.5 [mm]. The x-direction interval between the end of the antenna element 11 excluding the open end 115 on the −x direction side and the end 203 of the ground plane 20 facing the end is 2.0 [mm]. Become. The width of the open end 115 in the x direction (that is, the width protruding in the x direction) is 0.5 [mm].

The width in the y direction of each of the

conductor elements

121 and 123 is 0.5 [mm], and the distance in the y direction between the conductor element 121 and the conductor element 123 is 0.5 [mm]. Moreover, the space | interval of the y direction between the conductor element 123 and the edge part 201 of the ground plane 20 will be 0.5 [mm]. Moreover, the space | interval of the x direction between the edge part of the + x direction side except the open end 125 among the antenna elements 12 and the edge part 205 of the ground plane 20 facing the said edge part will be 2 [mm]. Further, the width of the open end 125 in the x direction (that is, the width protruding in the x direction) is 0.5 [mm].

The effective line length of the antenna element 11 is set so as to resonate at a frequency (that is, an operating frequency) belonging to the 2.4 GHz band. As a specific example, in the example illustrated in FIG. 4, the length from the feeding point 13 to the open end 115 in the conductor element 111 (referred to as “execution line length corresponding to the conductor element 111”), and a short circuit in the conductor element 113. Each of the lengths from the end 14 to the open end 115 (referred to as “execution line length corresponding to the conductor element 113”) corresponds to the effective line length of the antenna element 11. The effective line length corresponding to each of the

conductor elements

111 and 113 is set so as to satisfy the resonance condition for the antenna element 11 to resonate at the operating frequency (that is, the frequency belonging to the 2.4 GHz band). More specifically, when the wavelength corresponding to the operating frequency of the antenna element 11 is λ ₁ and an arbitrary integer of 0 or more is n, the effective line length of each of the

conductor elements

111 and 113 is expressed by the following conditional expression ( only to be designed to be substantially equal to the length L ₁ shown in 1).

In the antenna element 11, the lengths of the

conductor elements

111 and 113 that run parallel to each other along the x direction (that is, the lengths of the parts that are substantially parallel to each other) are expressed by the following conditional expression (2). It becomes substantially equal to the length La shown. In conditional expression (2), n ₀ represents an arbitrary integer of 0 or more.

Note that "substantially equal" length to the length L ₁ and La as described above, the antenna element VSWR (Voltage Standing Wave Ratio) is equivalent to the length of the range satisfying the VSWR <3. Here, the length of the range satisfying the condition of VSWR <3 is 20% of the center frequency when the frequency in the band to be transmitted / received (for example, in the 2.4 GHz band) is the center frequency. This is equivalent to a length that can ensure a sufficient bandwidth. More specifically, the length of the target, the indicated condition is the length shown above (e.g., the length L ₁ or La) so that the difference from the can, falls within a range of ± 8% of lambda _1/4 It is known that the condition of VSWR <3 is satisfied. As a more specific example, when paying attention to the lengths of the

conductor elements

111 and 113 that are parallel to each other along the x direction, the difference from the length L ₁ indicated by the conditional expression (2) shown above There so that the only to be designed to be within a range of ± 8% of λ _1/4.

Further, according to another viewpoint, although details will be described later, the antenna element 10 according to the present embodiment can be formed to have a thinner thickness in the y direction. From such characteristics, when the antenna element 10 is formed to have a smaller thickness in the y direction, the thickness in the y direction can be regarded as an error with respect to the width in the x direction. That is, the effective line length of the antenna element 11 and the lengths of the

conductor elements

111 and 113 that are parallel to each other along the x direction are regarded as being substantially equal (in other words, the lengths L ₁ and La described above are , L ₁ ≈La).

For example, in the example shown in FIG. 4, the lengths of the

conductor elements

111 and 113 that run parallel to each other along the x direction are set to 28.5 [mm]. Further, from the end on the + x direction side of the section in which the

conductor elements

111 and 113 run parallel to each other along the x direction, the vicinity of the electrically connected −x direction side end of the

conductor elements

121 and 123 The width in the x direction is 1.5 [mm]. Further, the width in the x direction between the end portion 205 of the base plate 20 and the position where the feeding point 13 is provided is 12 [mm].

Further, the effective line length of the antenna element 12 is set so as to resonate at a frequency (that is, an operating frequency) belonging to the 5 GHz band. As a specific example, in the example shown in FIG. 4, the length from the feeding point 13 to the open end 125 of the conductor element 121 via the conductor element 121 (“execution line length corresponding to the conductor element 121”) And the length from the feeding point 13 to the open end 125 of the conductor element 123 (referred to as “execution line length corresponding to the conductor element 123”) corresponds to the effective line length of the antenna element 12. To do. The effective line length corresponding to each of the

conductor elements

121 and 123 is set so that the antenna element 12 resonates at the operating frequency (that is, the frequency belonging to the 5 GHz band).

Here, the effective line length of the antenna element 12 is determined according to the length of each of the

conductor elements

121 and 123. The length of each of the

conductor elements

121 and 123 may be determined so as to resonate at the operating frequency of the antenna element 12 (that is, a frequency belonging to the 5 GHz band) by a prior experiment or simulation.

According to the antenna element 10 shown in FIG. 4, due to the influence of the antenna element 11 side, the length in the x direction of the antenna element 12 is set to the resonance condition at the operating frequency when the antenna element 12 is provided alone. It has been found that it is possible to set it shorter than the base length. Specifically, when the wavelength corresponding to the operating frequency of the antenna element 12 and lambda _2, the length of the portion running parallel to each other along the x direction in the conductive elements 121 and 123 (i.e., substantially parallel to each other the composed length of the portion) can be suppressed to less than λ _2/4. For example, when the operating frequency of the antenna element 12 is 5.15 [GHz], λ ₂ /4=14.5 [mm]. In contrast, in the example shown in FIG. 4, the length of the portion running parallel to each other along the x direction in the

conductive elements

121 and 123 is set to 11 [mm], with respect to lambda _2/4 It has been found that it can be set about -25% shorter.

With the configuration as described above, the current distribution of each of the

conductor elements

111 and 113 is in phase with each other when the antenna element 11 resonates at the operating frequency (that is, a frequency belonging to the 2.4 GHz band). For example, FIG. 5 shows a simulation result of current distribution in each part of the antenna element 10 when the antenna element 10 transmits a radio wave of 2.437 GHz. Note that the triangular marker in FIG. 5 indicates the direction in which current flows in the direction indicated by the apex in the long direction, and schematically indicates the amount of current by the size.

Specifically, in the example shown in FIG. 5, in the conductor element 111, the current that flows mainly in the direction opposite to the feed point 13 (that is, the −x direction side) with respect to the feed point 13. Are distributed. In the conductor element 113, a current that flows mainly in the direction opposite to the short-circuited end 14 (that is, the −x direction) with respect to the short-circuited end 14 (that is, the current reflected at the short-circuited end 14). ) Is distributed.

That is, in the example shown in FIG. 5, the currents flowing through the

conductor elements

111 and 113 that run parallel to each other in the x direction are in phase, and the current flowing through the conductor element 111 and the current flowing through the conductor element 113 strengthen each other. . For this reason, the antenna element 10 according to the present embodiment has the antenna element 90 according to the comparative example described above even if an induced current (that is, a current opposite to the current flowing through the conductor element 113) is induced on the ground plane 20 side. Compared to (see FIG. 3), it is possible to reduce the deterioration of sensitivity due to the influence of the induced current. Due to such characteristics, the antenna element 10 according to the present embodiment is further reduced in thickness in the y direction (ie, reduced in height) compared to the antenna element 90 according to the comparative example (see FIG. 3). Is possible.

In the example shown in FIG. 5, it can be seen that almost no current is distributed in the

conductor elements

121 and 123. That is, in the example shown in FIG. 5, it can be seen that the antenna element 12 side is not in resonance. In the above description, radio waves are transmitted. However, it goes without saying that the same applies to reception.

In addition, when the antenna element 12 resonates at the operating frequency (that is, a frequency belonging to the 5 GHz band), the current distributions of the

conductor elements

121 and 123 are in phase with each other. For example, FIG. 6 shows a simulation result of current distribution in each part of the antenna element 10 when the antenna element 10 transmits a radio wave of 5.24 GHz.

Specifically, in the example shown in FIG. 6, in the conductor element 121, a current flowing mainly toward the −x direction side is distributed. Also in the conductor element 123, a current flowing mainly toward the −x direction side is distributed.

In other words, in the example shown in FIG. 6, the currents flowing through the

conductor elements

121 and 123 that run parallel to each other in the x direction are in phase, and the current flowing through the conductor element 121 and the current flowing through the conductor element 123 strengthen each other. . Therefore, the antenna element 10 according to the present embodiment can reduce the deterioration of sensitivity due to the influence of the induced current flowing on the ground plane 20 side even when transmitting a radio wave of 5 GHz band.

In the example shown in FIG. 6, the current distributions of the conductor element 111 and the conductor element 113 are opposite to each other. Specifically, a current flowing mainly in the −x direction is distributed on the conductor element 111 side, and a current flowing mainly in the + direction is distributed on the conductor element 113 side. Therefore, in the example shown in FIG. 6, it can be seen that the current flowing through the conductor element 111 and the current flowing through the conductor element 113 cancel each other, and the antenna element 11 side does not resonate. In the above description, radio waves are transmitted. However, it goes without saying that the same applies to reception.

Here, in FIG. 7, as an example of the antenna characteristics of the antenna element 10 shown in FIG. 4, an example of a simulation result of the relationship between the frequency [GHz] of the transmission radio wave and the radiation efficiency [%] of the antenna element 10 is shown. Show. In FIG. 7, the horizontal axis indicates the frequency [GHz] of the transmission radio wave. The vertical axis represents the radiation efficiency [%] of the antenna element 10. Reference sign B11 schematically shows a frequency band of 2.4 GHz band in the wireless LAN. Similarly, reference sign B13 schematically shows a frequency band of 5 GHz band in the wireless LAN.

As shown in FIG. 7, according to the antenna element 10 according to the present embodiment, in the frequency band including the 2.4 GHz band indicated by the reference sign B11 and the frequency band including the 5 GHz band indicated by the reference sign B13. It can be seen that the radiation efficiency is higher.
