まず、本開示の一実施形態に係るアンテナ素子の特徴をよりわかりやすくするために、当該アンテナ素子を適用可能な情報処理装置の概略的な構成の一例について説明し、その後、本実施形態に係るアンテナ素子の課題について整理する。 <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.
例えば、図1は、本実施形態に係るアンテナ素子が適用され得る情報処理装置の概略的な構成の一例について説明するための説明図である。情報処理装置1は、所謂ウェアラブルデバイスとして構成されている。より具体的には、図1に示すように、情報処理装置1は、一部が開口したリング状の形状(換言すると、カチューシャ状、または、U字状の形状)を成し、リング状の部分の内面のうち少なくとも一部が、ユーザの首の一部に当接するように(即ち、首に掛けるように)当該ユーザに装着される。
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).
情報処理装置1は、例えば、ユーザに装着されたときに当該ユーザの耳の近傍に位置する部分に、所謂スピーカ等のような音響出力部を備え、当該音響出力部から音声等の音響情報を出力することで、当該音響情報をユーザに提示する。また、情報処理装置1は、例えば、ユーザに装着されたときに当該ユーザの口の近傍に位置する部分に、所謂マイクロフォンのような集音部を備え、当該集音部からユーザが発する音声を音響情報として集音する。
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.
また、情報処理装置1は、無線の通信経路を介して他の外部装置と通信を行うためのアンテナ素子10を筐体の内部に備える。例えば、図1に示す例では、アンテナ素子10は、当該情報処理装置1がユーザの首に装着されたときに、情報処理装置1の筐体のうち、ユーザの後頭部の近傍から、ユーザの首の側面に沿って前方に向けて延伸する部分の少なくとも一部に内蔵されている。
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.
ここで、図2を参照して、図1に示した情報処理装置1の筐体内にアンテナ素子10を内蔵する場合の実装例について説明する。図2は、本実施形態に係るアンテナ素子10の実装例について説明するための説明図である。なお、図2に示す例では、図面の横方向をx方向、図面の縦方向をy方向として説明する場合がある。また、図面の横方向(即ち、x方向)のうち左右を特に区別する場合には、右方向を+x方向、左方向を-x方向として説明する場合がある。同様に、図面の縦方向(即ち、y方向)のうち、上下を特に区別する場合には、上方向を+y方向、下方向を-y方向として説明する場合がある。
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.
図2において、参照符号20で示された長尺状の部材は、情報処理装置1の各種部品が実装される地板に相当する。当該地板20は、一部が開口したリング状の形状(換言すると、カチューシャ状、または、U字状の形状)に屈曲されて、情報処理装置1の筐体内に内蔵される。地板20の少なくとも一部には、アンテナ素子10が設けられている。地板20は、例えば、低抵抗のAu,Ag,Cu等の良導体や、Cuやリン青銅からなる導体薄板により形成され、アンテナ素子10に対してグラウンドの役割を果たす。例えば、図2に示す例では、地板20は、x方向に410[mm]、y方向に20[mm]の幅を有する。
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.
アンテナ素子10は、地板20に対して、エッチングなどの手法により、低抵抗のAu,Ag,Cu等の良導体や、Cuやリン青銅からなる導体薄板で形成される。また、アンテナ素子10は、情報処理装置1の筐体内に内蔵するために、x方向に410[mm]、y方向に20[mm]の範囲内に収まるように形成される必要がある。そのため、図2に示す例では、アンテナ素子10は、x方向に長尺状の形状を有するように形成されている。
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.
ここで、本実施形態に係るアンテナ素子10の特徴をよりわかりやすくするために、比較例として、図2に示す地板20に対して、所謂逆F型モノポールアンテナを設けた場合について説明することで、本実施形態に係るアンテナ素子10の課題について整理する。例えば、図3は、比較例に係るアンテナ素子90の構成の一例について説明するための説明図である。なお、図3に示す例では、図面の横方向は、図2に示したx方向に対応しており、図面の縦方向は、図2に示したy方向に対応している。
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.
図3に示すように、比較例に係るアンテナ素子90は、長尺状のアンテナエレメント91を有する、所謂モノポールアンテナとして構成されている。アンテナエレメント91は、参照符号94として示すように、長尺方向の一方の端部側が、地板20に対して電気的に接続されており、少なくとも一部を屈曲させることで、地板20に対して略平行となるように(即ち、-x方向に向けて延伸するように)設けられている。なお、このアンテナエレメント91のうち、参照符号94で示された、地板20に対して電気的に接続された部分を、「短絡端」と称する場合がある。また、アンテナエレメント91のx方向の端部のうち、短絡端94が設けられた側の端部近傍には給電点93が設けられている。給電点93においては、当該アンテナエレメント91の少なくとも一部が、地板20の近傍に、当該地板20に対して離隔するように設けられている。なお、アンテナエレメント91の長さは、動作周波数で共振が発生する長さとなっている。
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.
ここで、アンテナエレメント91には、給電点94から供給される高周波電力により電流が流れる。このとき、給電点94からアンテナエレメント91の当該給電点94とは逆側の端部に向けて流れる電流と、当該端部で反射した電流の構成との合成が、アンテナエレメント91における電流分布となる。
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.
ここで、アンテナエレメント91に対して、参照符号A1で示す方向に電流が流れているものとする。このとき、アンテナエレメント91を方向A1に向けて流れる電流により、地板20のうち当該アンテナエレメント91とx方向に向けて並走する部分に、方向A1とは逆側の方向A2に向けて誘導電流が発生する場合がある。この場合には、地板20側を方向A2に向けて流れる誘導電流(即ち、逆相の電流)により、アンテナエレメント91側を方向A1に向けて流れる電流が打ち消され、アンテナ素子90の感度が劣化する場合がある。このとき、地板20側を流れる誘導電流の影響は、アンテナエレメント91と地板20との間の幅が狭いほど強くなる傾向にある。そのため、比較例に係るアンテナ素子90のような構成では、アンテナエレメント91を、地板20に対してy方向に可能な限り離隔するように配置する必要があり、y方向の厚みをさらに薄くする(即ち、低背化する)ことが困難であった。
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.
そこで、本開示では、上記に説明したような課題を鑑みて、より低背化することが可能なアンテナ素子10と、当該アンテナ素子10を利用した情報処理装置1とを提案する。以降では、本実施形態に係るアンテナ素子10について、より詳しく説明する。
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.

First, an example of the configuration of the
図4に示すように、アンテナ素子10は、アンテナエレメント11と、アンテナエレメント12とを含む。
As shown in FIG. 4, the antenna element 10 includes an antenna element 11 and an antenna element 12.
アンテナエレメント11は、-x方向に延伸し、かつ、互いに略平行となるように設けられた長尺状の導体素子111及び113を含む。導体素子111及び113は、x方向に延伸するように設けられた地板20のy方向側の端部201に対して、y方向に離間して配置される。なお、本説明では、地板20と導体素子111との間に、導体素子113が介在するように、当該導体素子111及び113が配置されているものとして説明する。また、このとき、導体素子111及び113のそれぞれと、地板20の端部201とは、互いに略平行となる。なお、導体素子111が、「第1の部材」の一例に相当し、導体素子113が、「第2の部材」の一例に相当する。また、地板20が、「第3の部材」の一例に相当する。
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”.
図4に示す例では、導体素子111は、延伸方向の端部のうち、一方の端部(例えば、+x方向側の端部)が給電点13に対して電気的に接続されている。また、導体素子111は、他方の端部(例えば、-x方向側の端部)の近傍が、導体素子113の延伸方向の端部のうち、当該一方の端部と同じ方向の端部(即ち、-x方向側の端部)の近傍と電気的に接続されている。また、導体素子113は、参照符号14として示すように、導体素子111と電気的に接続された端部とは逆側の端部(即ち、+x方向側の端部)が、地板20に対して電気的に接続されている(即ち、短絡されている)。なお、以降は、参照符号14で示された、導体素子113と地板20とが短絡された部分を、「短絡端」と称する場合がある。
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”.
また、導体素子111は、導体素子113と電気的に接続されている側の端部の近傍に、-x方向(即ち、導体素子111及び113が並走する方向)に向けて突出するように開放端115が設けられている。同様に、導体素子113は、導体素子111と電気的に接続されている側の端部の近傍に、-x方向に向けて突出するように開放端115が設けられている。
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.
アンテナエレメント12は、アンテナエレメント11に対して+x方向側に位置するように設けられている。また、アンテナエレメント12は、+x方向に延伸し、かつ、互いに略平行となるように設けられた長尺状の導体素子121及び123を含む。導体素子121及び123は、地板20の端部201に対して、y方向に離間して配置される。なお、本説明では、地板20と導体素子121との間に、導体素子123が介在するように、当該導体素子121及び123が配置されているものとして説明する。また、このとき、導体素子121及び123のそれぞれと、地板20の端部201とは、互いに略平行となる。なお、導体素子121が、「第4の部材」の一例に相当し、導体素子123が、「第5の部材」の一例に相当する。
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”.
また、図4に示す例では、導体素子121の延伸方向の端部のうち、一方の端部(例えば、+x方向側の端部)の近傍と、導体素子123の延伸方向の端部のうち、当該一方の端部と同じ方向の端部(即ち、+x方向側の端部)の近傍とは、電気的に接続されている。同様に、導体素子121の他方の端部(即ち、-x方向側の端部)の近傍と、導体素子123の他方の端部(即ち、-x方向側の端部)の近傍とは、電気的に接続されている。即ち、導体素子121と導体素子123とが、ループ形状を成している。また、導体素子123の-x方向側の端部側は、給電点13に対して電気的に接続されている。なお、給電点13とは、アンテナ素子10のうち、給電部(もしくは、給電線)に対して電気的に接続された部分を示している。このような構成により、導体素子121の-x方向側の端部が、給電点13に対して電気的に接続されることとなる。
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.
また、導体素子121は、導体素子123と電気的に接続されている側の端部の近傍に、+x方向に向けて突出するように開放端125が設けられている。同様に、導体素子123は、導体素子121と電気的に接続されている側の端部の近傍に、+x方向に向けて突出するように開放端125が設けられている。また、導体素子123は、-x方向側の端部の近傍にも、-x方向に向けて突出するように開放端125が設けられている。
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.
なお、図4に示す例では、アンテナ素子10は、導体素子111の+x方向側の端部と、導体素子121の-x方向側の端部とが接続されるように、アンテナエレメント11とアンテナエレメント12とが一体的に形成されている。このような構成により、導体素子111の+x方向側の端部が、給電点13に対して電気的に接続されることとなる。
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.
また、図4に示す例では、アンテナエレメント11と、アンテナエレメント12とは、互いに異なる周波数帯の電波を送受信可能に構成されている。具体的には、アンテナエレメント11は、無線LAN等で使用される周波数帯のうち、2.4GHz帯の電波を送受信可能に構成されている。そのため、アンテナエレメント11が、2.4GHz帯に属する周波数(即ち、動作周波数)で共振するように、当該アンテナエレメント11の各部のサイズが設定されている。同様に、アンテナエレメント12は、無線LAN等で使用される周波数帯のうち、5GHz帯の電波を送受信可能に構成されている。そのため、アンテナエレメント12が、5GHz帯に属する周波数(即ち、動作周波数)で共振するように、当該アンテナエレメント12の各部のサイズが設定されている。
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.
例えば、図4に示す例では、アンテナ素子10は、開放端115及び125を含むx方向の幅が42[mm]、y方向の幅が2[mm]となるように構成されている。なお、図4に示す例では、アンテナ素子10のy方向の幅は、アンテナエレメント11の動作周波数(即ち、2.4GHz帯に属する周波数)に対応する波長の略1/60となっている。
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).
導体素子111及び113それぞれのy方向の幅は0.5[mm]であり、導体素子111と導体素子113との間のy方向の間隔は0.5[mm]となる。また、導体素子113と地板20の端部201との間のy方向の間隔は0.5[mm]となる。また、アンテナエレメント11のうち、開放端115を除く-x方向側の端部と、当該端部と対向する地板20の端部203との間のx方向の間隔は2.0[mm]となる。また、開放端115のx方向の幅(即ち、x方向に突出する幅)は0.5[mm]となる。
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].
また、導体素子121及び123それぞれのy方向の幅は0.5[mm]であり、導体素子121と導体素子123との間のy方向の間隔は0.5[mm]となる。また、導体素子123と地板20の端部201との間のy方向の間隔は0.5[mm]となる。また、アンテナエレメント12のうち、開放端125を除く+x方向側の端部と、当該端部と対向する地板20の端部205との間のx方向の間隔は2[mm]となる。また、開放端125のx方向の幅(即ち、x方向に突出する幅)は0.5[mm]となる。
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].
また、アンテナエレメント11の実効線路長は、2.4GHz帯に属する周波数(即ち、動作周波数)で共振するように設定される。具体的な一例として、図4に示す例では、導体素子111における給電点13から開放端115までの長さ(「導体素子111に対応する実行線路長」とする)と、導体素子113における短絡端14から開放端115までの長さ(「導体素子113に対応する実行線路長」とする)とのそれぞれが、アンテナエレメント11の実効線路長に相当する。この導体素子111及び113それぞれに対応する実効線路長が、アンテナエレメント11が動作周波数(即ち、2.4GHz帯に属する周波数)で共振するための共振条件を満たすように設定される。より具体的には、アンテナエレメント11の動作周波数に対応する波長をλ1、0以上の任意の整数をnとした場合に、導体素子111及び113それぞれの実効線路長が、以下の条件式(1)で示された長さL1と略等しくなるように設計されればよい。
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).
また、アンテナエレメント11は、導体素子111及び113のうちx方向に沿って互いに並走する部分の長さ(即ち、互いに略平行となる部分の長さ)が、以下の条件式(2)で示される長さLaと略等しくなる。なお、条件式(2)において、n0は0以上の任意の整数を示すものとする。
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.
なお、上記に説明した長さL1及びLaに「略等しい」長さとは、アンテナエレメントのVSWR(Voltage Standing Wave Ratio)が、VSWR<3の条件を満たす範囲の長さに相当する。ここで、VSWR<3の条件を満たす範囲の長さとは、送受信の対象となる帯域中(例えば、2.4GHz帯中)の周波数を中心周波数とした場合に、当該中心周波数に対して20%のバンド幅を確保可能な長さに相当する。より具体的には、対象の長さが、上記に示した条件式が示す長さ(例えば、長さL1またはLa)に対する差が、λ1/4の±8%の範囲内となるように設計されれば、VSWR<3の条件を満たすことがわかっている。より具体的な一例として、導体素子111及び113のうちx方向に沿って互いに並走する部分の長さに着目した場合に、上記に示した条件式(2)が示す長さL1に対する差がλ1/4の±8%の範囲内となるように設計されればよいこととなる。
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.
また、別の観点に依れば、詳細は後述するが、本実施形態に係るアンテナ素子10は、y方向の厚みをより薄く形成することが可能である。このような特性から、アンテナ素子10は、y方向の厚みをより薄く形成した場合には、x方向の幅に対してy方向の厚みを誤差としてみなすことが可能となる。即ち、アンテナエレメント11の実効線路長と、導体素子111及び113のうちx方向に沿って互いに並走する部分の長さとが略等しいものとみなす(換言すると、前述した長さL1及びLaを、L1≒Laとみなす)ことも可能となる。
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).
例えば、図4に示す例では、導体素子111及び113のうちx方向に沿って互いに並走する部分の長さが28.5[mm]に設定されている。また、導体素子111及び113がx方向に沿って互いに並走する区間の+x方向側の端部から、導体素子121及び123のうち電気的に接続された-x方向側の端部の近傍との間のx方向の幅が1.5[mm]となる。また、地板20の端部205と給電点13が設けられた位置との間のx方向の幅が12[mm]となる。
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].
また、アンテナエレメント12の実効線路長は、5GHz帯に属する周波数(即ち、動作周波数)で共振するように設定される。具体的な一例として、図4に示す例では、給電点13から導体素子121を介して当該導体素子121の開放端125に至るまでの長さ(「導体素子121に対応する実行線路長」とする)と、給電点13から導体素子123の開放端125に至るまでの長さ(「導体素子123に対応する実行線路長」とする)とのそれぞれが、アンテナエレメント12の実効線路長に相当する。この導体素子121及び123のそれぞれに対応する実効線路長が、アンテナエレメント12が動作周波数(即ち、5GHz帯に属する周波数)で共振するように設定されることとなる。
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).
ここで、アンテナエレメント12の実効線路長は、導体素子121及び123それぞれの長さに応じて決定されることとなる。導体素子121及び123それぞれの長さについては、事前の実験やシミュレーション等により、アンテナエレメント12の動作周波数(即ち、5GHz帯に属する周波数)で共振するように決定されるとよい。
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.
なお、図4に示すアンテナ素子10に依れば、アンテナエレメント11側の影響により、アンテナエレメント12のx方向の長さを、当該アンテナエレメント12を単体で設ける場合における動作周波数での共振条件に基づく長さよりも短く設定することが可能であることがわかっている。具体的には、アンテナエレメント12の動作周波数に対応する波長をλ2とした場合に、導体素子121及び123のうちx方向に沿って互いに並走する部分の長さ(即ち、互いに略平行となる部分の長さ)を、λ2/4未満に抑えることが可能である。例えば、アンテナエレメント12の動作周波数を5.15[GHz]とした場合には、λ2/4=14.5[mm]となる。これに対して、図4に示す例では、導体素子121及び123のうちx方向に沿って互いに並走する部分の長さが11[mm]に設定されており、λ2/4に対して約-25%短く設定できることがわかっている。
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.
以上のような構成により、アンテナエレメント11は、動作周波数(即ち、2.4GHz帯に属する周波数)での共振時に、導体素子111及び113それぞれの電流分布が互いに同相となる。例えば、図5は、アンテナ素子10に、2.437GHzの電波を送信させた場合の、当該アンテナ素子10の各部における電流分布のシミュレーション結果を示している。なお、図5中の三角形状のマーカは、長尺方向の頂点が指し示す方向により電流が流れる方向を示し、大きさにより電流量を模式的に示している。
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.
具体的には、図5に示す例では、導体素子111において、主に、給電点13に対して、当該給電点13とは逆側の方向(即ち、-x方向側)に向けて流れる電流が分布している。また、導体素子113においては、主に、短絡端14に対して、当該短絡端14とは逆側の方向(即ち、-x方向)に向けて流れる電流(即ち、短絡端14において反射した電流)が分布している。
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.
即ち、図5に示す例では、x方向に向けて互いに並走する導体素子111及び113それぞれに流れる電流が同相となり、導体素子111を流れる電流と、導体素子113を流れる電流とが互いに強めあう。そのため、本実施形態に係るアンテナ素子10は、地板20側に誘導電流(即ち、導体素子113を流れる電流とは逆向きの電流)が誘起されたとしても、前述した比較例に係るアンテナ素子90(図3参照)に比べて、当該誘導電流の影響による感度の劣化を低減することが可能となる。このとような特性から、本実施形態に係るアンテナ素子10は、比較例に係るアンテナ素子90(図3参照)に比べて、y方向の厚みをさらに薄くする(即ち、低背化する)ことが可能となる。
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.
また、図5に示す例では、導体素子121及び123に電流がほとんど分布していないことがわかる。即ち、図5に示す例では、アンテナエレメント12側は、共振していない状態であることがわかる。なお、上記では、電波の送信時について説明したが、受信時においても同様であることは言うまでもない。
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.
また、アンテナエレメント12は、動作周波数(即ち、5GHz帯に属する周波数)での共振時に、導体素子121及び123それぞれの電流分布が互いに同相となる。例えば、図6は、アンテナ素子10に、5.24GHzの電波を送信させた場合の、当該アンテナ素子10の各部における電流分布のシミュレーション結果を示している。
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.
具体的には、図6に示す例では、導体素子121において、主に、-x方向側に向けて流れる電流が分布している。また、導体素子123においても、主に、-x方向側に向けて流れる電流が分布している。
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.
即ち、図6に示す例では、x方向に向けて互いに並走する導体素子121及び123それぞれに流れる電流が同相となり、導体素子121を流れる電流と、導体素子123を流れる電流とが互いに強めあう。そのため、本実施形態に係るアンテナ素子10は、5GHz帯の電波の送信時においても、地板20側を流れる誘導電流の影響による感度の劣化を低減することが可能となること。
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.
また、図6に示す例では、導体素子111と導体素子113とは、電流分布が互いに逆相となる。具体的には、導体素子111側には、主に-x方向に向けて流れる電流が分布し、導体素子113側には、主に+方向に向けて流れる電流が分布することとなる。そのため、図6に示す例では、導体素子111を流れる電流と、導体素子113を流れる電流とが打ち消しあい、アンテナエレメント11側は、共振しない状態であることがわかる。なお、上記では、電波の送信時について説明したが、受信時においても同様であることは言うまでもない。
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.
ここで、図7に、図4に示すアンテナ素子10のアンテナ特性の一例として、送信電波の周波数[GHz]と、アンテナ素子10の放射効率[%]との間の関係のシミュレーション結果の一例を示す。図7において、横軸は、送信電波の周波数[GHz]を示している。また、縦軸は、アンテナ素子10の放射効率[%]を示している。また、参照符号B11は、無線LANにおける2.4GHz帯の周波数帯域を模式的に示している。同様に、参照符号B13は、無線LANにおける5GHz帯の周波数帯域を模式的に示している。
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.
図7に示すように、本実施形態に係るアンテナ素子10に依れば、参照符号B11で示した2.4GHz帯を含む周波数帯域と、参照符号B13で示した5GHz帯を含む周波数帯域とにおいて、より高い放射効率を示していることがわかる。
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.

次に、変形例2として、本実施形態に係るアンテナ素子の構成の一例について説明する。なお、本説明では、特徴的な部分をよりわかりやすくするために、本実施形態に係るアンテナ素子がシングルバンドアンテナとして構成されている場合を例に説明するが、図4に示すように、マルチバンドアンテナとして構成されている場合についても同様である。 [4.2. Modification Example 2: Configuration Example of Antenna Element]
Next, as a second modification, an example of the configuration of the antenna element according to the present embodiment will be described. In this description, in order to make the characteristic part easier to understand, a case where the antenna element according to the present embodiment is configured as a single band antenna will be described as an example. However, as shown in FIG. The same applies to the case of being configured as a band antenna.
例えば、図10は、変形例2に係るアンテナ素子の概略的な構成の一例について説明するための説明図である。図10に示すアンテナ素子50において、導体素子511及び513は、前述した変形例1に係るアンテナ素子40(図9参照)における導体素子411及び413に対応している。また、図10に示すアンテナ素子50において、給電点53及び短絡端54は、前述した変形例1に係るアンテナ素子40における給電点43及び短絡端44に対応している。
For example, FIG. 10 is an explanatory diagram for explaining an example of a schematic configuration of an antenna element according to Modification 2. In the antenna element 50 shown in FIG. 10, the conductor elements 511 and 513 correspond to the conductor elements 411 and 413 in the antenna element 40 (see FIG. 9) according to Modification 1 described above.

より具体的には、図10に示す例では、アンテナ素子50は、地板20が延伸する方向(x方向)に向けて延伸し、かつ、互いに略平行となるように設けられた導体素子511及び513を含む。このとき、導体素子511及び513のうちx方向に向けて互いに並走する部分は、x方向に延伸する地板20に対して略平行となるように配置されている。また、導体素子513は、+x方向側の端部が地板20と電気的に接続されており(即ち、短絡端54が設けられており)、-x方向側の端部近傍が、導体素子511の-x方向側の端部近傍と電気的に接続されている。また、導体素子511及び513それぞれの、-x方向側の端部には、開放端515が設けられている。これらの構成については、図10に示すアンテナ素子50は、図9を参照して前述した変形例1に係るアンテナ素子40と同様である。
More specifically, in the example shown in FIG. 10, the antenna element 50 extends in the direction (x direction) in which the ground plane 20 extends, and the conductor elements 511 are provided so as to be substantially parallel to each other. 513. At this time, portions of the conductor elements 511 and 513 that run parallel to each other in the x direction are disposed so as to be substantially parallel to the ground plane 20 extending in the x direction. The conductor element 513 has an end on the + x direction side electrically connected to the ground plane 20 (that is, a short-circuit end 54 is provided), and the vicinity of the end on the −x direction side is the conductor element 511. Is electrically connected to the vicinity of the end on the −x direction side. In addition, an open end 515 is provided at each end of the conductor elements 511 and 513 on the −x direction side. About these structures, the antenna element 50 shown in FIG. 10 is the same as the antenna element 40 which concerns on the modification 1 mentioned above with reference to FIG.
一方で、図10に示すアンテナ素子50は、導体素子511の-x方向側の端部が給電点53に接続されているものの、導体素子511及び513に対する給電点53の相対的な位置が、前述した変形例1に係るアンテナ素子40(図9参照)と異なる。
On the other hand, in the antenna element 50 shown in FIG. 10, although the end of the conductor element 511 on the −x direction side is connected to the feeding point 53, the relative position of the feeding point 53 with respect to the conductor elements 511 and 513 is It differs from the antenna element 40 (refer FIG. 9) which concerns on the modification 1 mentioned above.
このように、本実施形態に係るアンテナ素子は、地板20に対する各導体素子(例えば、導体素子511及び513)の位置関係と、給電点、各導体素子、及び地板20間の電気的な接続関係と、各導体素子間が互いに並走する部分の長さの関係と、実効線路長の関係とが、前述した各実施形態に係るアンテナ素子と同様であれば、給電点を設ける位置等のようなその他の構成については特に限定されない。
As described above, the antenna element according to this embodiment includes the positional relationship of each conductor element (for example, the conductor elements 511 and 513) with respect to the ground plane 20 and the electrical connection relationship between the feeding point, each conductor element, and the ground plane 20. If the relationship between the lengths of the portions where the conductor elements run parallel to each other and the relationship between the effective line lengths are the same as those of the antenna elements according to each of the embodiments described above, the position of the feeding point, etc. Other configurations are not particularly limited.
もちろん、各導体素子の配線方法の一部を変更してもよい。例えば、図11は、変形例2に係るアンテナ素子の概略的な構成の他の一例について説明するための説明図である。図11に示すアンテナ素子60において、導体素子611及び613は、前述した変形例1に係るアンテナ素子40(図9参照)における導体素子411及び413に対応している。また、図11に示すアンテナ素子60において、給電点63及び短絡端64は、前述した変形例1に係るアンテナ素子40における給電点43及び短絡端44に対応している。即ち、図11に示すアンテナ素子60は、地板20に対する各導体素子の位置関係と、給電点、各導体素子、及び地板20間の電気的な接続関係と、各導体素子間の長さ及び実効線路の長さの関係とが、前述した変形例1に係るアンテナ素子40と同様となるように構成されている。
Of course, you may change a part of wiring method of each conductor element.

That is, the antenna element 60 shown in FIG. 11 has a positional relationship of each conductor element with respect to the ground plane 20, an electrical connection relationship between the feeding point, each conductor element, and the ground plane 20, a length between each conductor element and an effective value. The line length relationship is configured to be the same as that of the antenna element 40 according to Modification 1 described above.
一方で、図11に示すアンテナ素子60は、導体素子611と給電点63との間を接続する部分と、導体素子613の一部とが、交差するように配線されている点で、前述した変形例1に係るアンテナ素子40と異なる。なお、図11に示す例では、当該各配線が交差する部分については、当該配線間が電気的に接続されないように、例えば、絶縁材料等を介在させることで絶縁されている。このように、各導体素子のうち、地板20に対して、当該地板20が延伸する方向(x方向)に互いに並走する部分以外については、実効線路の長さの条件を満たす範囲内において適宜変更してもよい。
On the other hand, the antenna element 60 shown in FIG. 11 is described above in that a portion connecting the conductor element 611 and the feeding point 63 and a part of the conductor element 613 are wired so as to intersect each other. Different from the antenna element 40 according to the first modification. In the example shown in FIG. 11, the portions where the wirings intersect are insulated by interposing an insulating material or the like so that the wirings are not electrically connected. As described above, the portions of the conductor elements other than the portions parallel to each other in the direction in which the ground plane 20 extends (x direction) with respect to the ground plane 20 are appropriately within the range that satisfies the condition of the effective line length. It may be changed.

図12に示すように、変形例3に係るアンテナ素子70は、互いに異なる周波数帯の電波を送受信可能に構成された、アンテナエレメント71と、アンテナエレメント72とを含む。アンテナエレメント71は、前述した実施形態に係るアンテナ素子10(図4参照)におけるアンテナエレメント11に対応している。より具体的には、導体素子711、導体素子713、及び開放端715は、前述した実施形態に係るアンテナ素子10における、導体素子111、導体素子113、及び開放端115に対応している。また、図12に示すアンテナ素子70において、給電点73及び短絡端74は、前述した実施形態に係るアンテナ素子10における給電点13及び短絡端14に対応している。なお、アンテナ素子70におけるアンテナエレメント71と、前述した実施形態に係るアンテナ素子10におけるアンテナエレメント11とは、基本的な構成は同様である。
As shown in FIG. 12, the antenna element 70 according to the modification 3 includes an antenna element 71 and an antenna element 72 configured to be able to transmit and receive radio waves in different frequency bands. The antenna element 71 corresponds to the antenna element 11 in the antenna element 10 (see FIG. 4) according to the above-described embodiment. More specifically, the conductor element 711, the conductor element 713, and the open end 715 correspond to the conductor element 111, the conductor element 113, and the open end 115 in the antenna element 10 according to the above-described embodiment. Further, in the antenna element 70 shown in FIG. 12, the feeding point 73 and the short-circuit end 74 correspond to the feeding point 13 and the short-circuit end 14 in the antenna element 10 according to the above-described embodiment. The basic configuration of the antenna element 71 in the antenna element 70 and the antenna element 11 in the antenna element 10 according to the above-described embodiment are the same.
また、アンテナエレメント72は、前述した実施形態に係るアンテナ素子10(図4参照)におけるアンテナエレメント12に対応している。一方で、変形例3に係るアンテナ素子70は、アンテナエレメント72の構成が、前述した実施形態に係るアンテナ素子10(図4参照)と異なる。そこで、本説明では、変形例3に係るアンテナ素子70の特徴として、特に、アンテナエレメント72の構成に着目して説明する。
The antenna element 72 corresponds to the antenna element 12 in the antenna element 10 (see FIG. 4) according to the above-described embodiment. On the other hand, the antenna element 70 according to Modification 3 is different from the antenna element 10 according to the above-described embodiment (see FIG. 4) in the configuration of the antenna element 72. Therefore, in this description, the feature of the antenna element 70 according to Modification 3 will be described with particular attention paid to the configuration of the antenna element 72.
アンテナエレメント72は、地板20が延伸する方向(x方向)に向けて延伸し、かつ、互いに略平行となるように設けられた導体素子721及び723を含む。このとき、導体素子721及び723のうちx方向に向けて互いに並走する部分は、x方向に延伸する地板20に対して略平行となるように配置されている。また、導体素子721は、-x方向側の端部が給電点73に接続されており、+x方向側の端部近傍が、導体素子723の+x方向側の端部近傍と電気的に接続されている。また、導体素子723の-x方向側の端部は、地板20に対して短絡端74とは異なる部分で電気的に接続されている(即ち、短絡端74とは異なる他の短絡端74’が別途設けられている)。また、導体素子721及び723それぞれの、+x方向側の端部には、開放端725が設けられている。
The antenna element 72 includes conductor elements 721 and 723 that extend in a direction (x direction) in which the ground plane 20 extends and are provided to be substantially parallel to each other. At this time, portions of the conductor elements 721 and 723 that run parallel to each other in the x direction are arranged so as to be substantially parallel to the ground plane 20 extending in the x direction. The end of the conductor element 721 on the −x direction side is connected to the feeding point 73, and the vicinity of the end on the + x direction side is electrically connected to the vicinity of the end of the conductor element 723 on the + x direction side. ing. The end of the conductor element 723 on the −x direction side is electrically connected to the ground plane 20 at a portion different from the short-circuit end 74 (that is, another short-circuit end 74 ′ different from the short-circuit end 74). Is provided separately). In addition, an open end 725 is provided at each end of the conductor elements 721 and 723 on the + x direction side.
また、アンテナエレメント72の実効線路長は、当該アンテナエレメント72の動作周波数で共振するように設定される。具体的な一例として、図12に示す例では、導体素子721における給電点73から開放端725までの長さ(「導体素子721に対応する実行線路長」とする)と、導体素子713における短絡端74’から開放端725までの長さ(「導体素子723に対応する実行線路長」とする)とのそれぞれが、アンテナエレメント72の実効線路長に相当する。この導体素子721及び723のそれぞれに対応する実効線路長が、アンテナエレメント72が動作周波数で共振するための共振条件を満たすように設定される。
The effective line length of the antenna element 72 is set so as to resonate at the operating frequency of the antenna element 72. As a specific example, in the example shown in FIG. 12, the length from the feeding point 73 to the open end 725 in the conductor element 721 (referred to as “execution line length corresponding to the conductor element 721”) and the short circuit in the conductor element 713. Each of the length from the end 74 ′ to the open end 725 (“execution line length corresponding to the conductor element 723”) corresponds to the effective line length of the antenna element 72. The effective line length corresponding to each of the conductor elements 721 and 723 is set so as to satisfy the resonance condition for the antenna element 72 to resonate at the operating frequency.
なお、アンテナエレメント72においては、図4を参照して前述したアンテナエレメント11(即ち、図12におけるアンテナエレメント71)と同様に、実効線路長や、導体素子721及び723のうちx方向に沿って互いに並走する部分の長さが決定されればよい。即ち、アンテナエレメント72の実効線路長については、前述した条件式(1)に対して、動作周波数に基づく波長を代入することで算出される長さL1と略等しくなるように設定されればよい。また、導体素子721及び723のうちx方向に沿って互いに並走する部分の長さ(即ち、互いに略平行となる部分の長さ)については、前述した条件式(2)に対して、動作周波数に基づく波長を代入することで算出される長さL1と略等しくなるように設定されればよい。
Note that, in the antenna element 72, the effective line length and the conductor elements 721 and 723 along the x direction are the same as the antenna element 11 described above with reference to FIG. 4 (that is, the antenna element 71 in FIG. 12). The lengths of the parts that run parallel to each other need only be determined. That is, for the effective line length of the antenna element 72, if it is set so as for the condition expressions described above (1), it becomes approximately equal to the length L 1 which is calculated by substituting the wavelength based the operating frequency Good. The lengths of the conductor elements 721 and 723 that run parallel to each other along the x direction (that is, the lengths of the parts that are substantially parallel to each other) operate according to the conditional expression (2) described above. may be employed to the length L 1 and set to be substantially equal it can be determined by substituting a wavelength based on the frequency.
以上のような構成により、アンテナ素子70は、2つの周波数帯を利用することが可能なマルチバンドアンテナとして動作することが可能となる。なお、この場合には、2つの周波数帯のうち、一方の周波数帯(例えば、2.4GHz帯)を利用する場合には、アンテナエレメント71側が共振し、他方の周波数帯(例えば、5GHz帯)を利用する場合には、アンテナエレメント72側が共振することとなる。
With the above configuration, the antenna element 70 can operate as a multiband antenna that can use two frequency bands. In this case, when one frequency band (for example, 2.4 GHz band) is used, the antenna element 71 side resonates and the other frequency band (for example, 5 GHz band) is used. When the antenna element is used, the antenna element 72 side resonates.
以上、変形例3として、図12を参照して、本実施形態に係るアンテナ素子がマルチバンドアンテナとして構成されている場合における、当該アンテナ素子の構成の一例について説明する。
As described above, as Modification 3, an example of the configuration of the antenna element when the antenna element according to the present embodiment is configured as a multiband antenna will be described with reference to FIG.
<5.まとめ>
以上、説明したように、本実施形態に係るアンテナ素子10は、例えば、図4に示すように、地板20が延伸する方向(x方向)に向けて延伸し、かつ、互いに略平行となるように設けられた導体素子111及び113を含むアンテナエレメント11を備える。このとき、導体素子111及び113のうちx方向に向けて互いに並走する部分は、x方向に延伸する地板20に対して略平行となるように配置されている。また、アンテナエレメント11は、動作周波数での共振時に、導体素子111及び113それぞれの電流分布が同相となるように、当該導体素子111及び113の長さ(特に、x方向に向けて並走する部分の長さ)が設定されている。このような構成により、アンテナ素子10は、導体素子111及び113それぞれを流れる電流が互いに強めあい、地板20側に誘導電流が誘起されたとしても、前述した比較例に係るアンテナ素子90(図3参照)に比べて、当該誘導電流の影響による感度の劣化を低減することが可能となる。即ち、本実施形態に係るアンテナ素子10は、比較例に係るアンテナ素子90(図3参照)に比べて、y方向の厚みをさらに薄くする(即ち、低背化する)ことが可能となる。 <5. Summary>
As described above, theantenna element 10 according to the present embodiment extends in the direction (x direction) in which the ground plane 20 extends and is substantially parallel to each other, for example, as shown in FIG. The antenna element 11 including the conductor elements 111 and 113 provided in the antenna is provided. At this time, portions of the conductor elements 111 and 113 that run parallel to each other in the x direction are arranged so as to be substantially parallel to the ground plane 20 extending in the x direction. Further, the antenna element 11 runs in parallel in the lengths of the conductor elements 111 and 113 (particularly in the x direction) so that the current distributions of the conductor elements 111 and 113 are in phase during resonance at the operating frequency. (Length of part) is set. With such a configuration, the antenna element 10 has the antenna element 90 (see FIG. 3) according to the comparative example described above even if the currents flowing through the conductor elements 111 and 113 are strengthened and an induced current is induced on the ground plane 20 side. Compared to the reference), it is possible to reduce the deterioration of sensitivity due to the influence of the induced current. That is, the antenna element 10 according to the present embodiment can further reduce the thickness in the y direction (that is, reduce the height) compared to the antenna element 90 according to the comparative example (see FIG. 3).
以上、説明したように、本実施形態に係るアンテナ素子10は、例えば、図4に示すように、地板20が延伸する方向(x方向)に向けて延伸し、かつ、互いに略平行となるように設けられた導体素子111及び113を含むアンテナエレメント11を備える。このとき、導体素子111及び113のうちx方向に向けて互いに並走する部分は、x方向に延伸する地板20に対して略平行となるように配置されている。また、アンテナエレメント11は、動作周波数での共振時に、導体素子111及び113それぞれの電流分布が同相となるように、当該導体素子111及び113の長さ(特に、x方向に向けて並走する部分の長さ)が設定されている。このような構成により、アンテナ素子10は、導体素子111及び113それぞれを流れる電流が互いに強めあい、地板20側に誘導電流が誘起されたとしても、前述した比較例に係るアンテナ素子90(図3参照)に比べて、当該誘導電流の影響による感度の劣化を低減することが可能となる。即ち、本実施形態に係るアンテナ素子10は、比較例に係るアンテナ素子90(図3参照)に比べて、y方向の厚みをさらに薄くする(即ち、低背化する)ことが可能となる。 <5. Summary>
As described above, the
また、本実施形態に係るアンテナ素子10は、互いに異なる周波数帯の電波を送受信可能に構成されたアンテナエレメント11及び12を、地板20が延伸する方向(x方向)に並べて配置されるように構成することが可能である。このような構成により、本実施形態に係るアンテナ素子10は、マルチバンドアンテナとして構成する場合においても、y方向の厚みがより薄くなるように構成する(即ち、低背化する)ことが可能となる。
Further, the antenna element 10 according to the present embodiment is configured such that antenna elements 11 and 12 configured to be able to transmit and receive radio waves in different frequency bands are arranged side by side in a direction (x direction) in which the ground plane 20 extends. Is possible. With such a configuration, the antenna element 10 according to the present embodiment can be configured such that the thickness in the y direction is thinner (that is, the profile can be reduced) even when configured as a multiband antenna. Become.
また、上記に説明したように、本実施形態に係るアンテナ素子10は、厚みがより薄くなるように形成することが可能なため、多様な態様の機器(情報処理装置)に対して適用することが可能である。例えば、図13は、本実施形態に係るアンテナ素子10の他の適用例について説明するための図であり、当該アンテナ素子10を、所謂時計型のウェアラブルデバイスとして構成された情報処理装置1aに適用した場合の一例を示している。例えば、図13に示す情報処理装置1aでは、各種素子が実装される基板の端部にアンテナ素子10が設けられることで、本体の筐体内のうち端部の近傍に内蔵されている。もちろん、本実施形態に係るアンテナ素子10が適用される機器(情報処理装置)の態様は特に限定されない。具体的な一例として、アンテナ素子10は、スマートフォンやタブレット端末のような情報処理装置に適用されていてもよい。
Further, as described above, the antenna element 10 according to the present embodiment can be formed to have a smaller thickness, and therefore can be applied to various types of devices (information processing apparatuses). Is possible. For example, FIG. 13 is a diagram for explaining another application example of the antenna element 10 according to the present embodiment, and the antenna element 10 is applied to an information processing apparatus 1a configured as a so-called watch-type wearable device. An example of the case is shown. For example, in the information processing apparatus 1a shown in FIG. 13, the antenna element 10 is provided at the end portion of the substrate on which various elements are mounted, so that it is built in the vicinity of the end portion in the housing of the main body. Of course, the aspect of the apparatus (information processing apparatus) to which the antenna element 10 according to the present embodiment is applied is not particularly limited. As a specific example, the antenna element 10 may be applied to an information processing apparatus such as a smartphone or a tablet terminal.
また、上記説明では、本実施形態に係るアンテナ素子10を、例えば、無線LANで使用する周波数帯の電波を送受信可能に構成する場合について説明したが、送受信の対象となる周波数帯は、必ずしも無線LANで使用される周波数帯には限定されない。具体的な一例として、アンテナ素子10を、所謂LTE(Long Term Evolution)等の通信規約に基づき動作するセルラーで使用される周波数帯(例えば、800MHz帯、1.5GHz帯、及び2GHz帯)の電波が送受信可能となるように構成してもよい。なお、この場合には、各アンテナエレメントにおける各導体素子間が互いに並走する部分の長さと、実効線路長とを、当該アンテナエレメントの動作周波数に応じて適宜調整すればよいことは言うまでもない。
In the above description, the antenna element 10 according to the present embodiment is described as being configured to be able to transmit and receive radio waves in a frequency band used in a wireless LAN, but the frequency band to be transmitted and received is not necessarily wireless. The frequency band used in the LAN is not limited. As a specific example, the antenna element 10 is a radio wave in a frequency band (for example, 800 MHz band, 1.5 GHz band, and 2 GHz band) used in a cellular system that operates based on a communication protocol such as so-called LTE (Long Term Evolution). May be configured to be able to transmit and receive. In this case, needless to say, the length of the portion of each antenna element in which the conductor elements run parallel to each other and the effective line length may be appropriately adjusted according to the operating frequency of the antenna element.
