Description

アンテナモジュール、電子機器及び非接触通信方法Antenna module, electronic equipment and non-contact communication method
　本発明は、アンテナモジュール、電子機器及び非接触通信方法に関する。 The present invention relates to an antenna module, an electronic device, and a non-contact communication method.
　従来のアンテナモジュールが下記特許文献１に記載されている。このモジュールは、基板と、第１ループアンテナと、第２ループアンテナとを備えている。第１ループアンテナ及び第２ループアンテナは、基板の同一面上に同心円状に設けられている。第１ループアンテナ及び第２ループアンテナの各々が、一対の端子部を有している。第１ループアンテナ及び第２ループアンテナの各々に信号が入力され、第１ループアンテナ及び第２ループアンテナの各々によって非接触通信がなされている。 The conventional antenna module is described in Patent Document 1 below. This module includes a substrate, a first loop antenna, and a second loop antenna. The first loop antenna and the second loop antenna are concentrically provided on the same surface of the substrate. Each of the first loop antenna and the second loop antenna has a pair of terminals. A signal is input to each of the first loop antenna and the second loop antenna, and non-contact communication is performed by each of the first loop antenna and the second loop antenna.
特開２０１６－１００８７２号公報Japanese Unexamined Patent Publication No. 2016-100872
　第１ループアンテナ及び第２ループアンテナを用いて同時に非接触通信を行う場合、上記の通り、第１ループアンテナ及び第２ループアンテナは同心円状に配置されているため、第１ループアンテナから生じたノイズが第２ループアンテナの非接触通信に干渉したり、第２ループアンテナから生じたノイズが第１ループアンテナの非接触通信に干渉したりする。 When non-contact communication is performed simultaneously using the first loop antenna and the second loop antenna, the first loop antenna and the second loop antenna are arranged concentrically as described above, so that the first loop antenna is generated. The noise interferes with the non-contact communication of the second loop antenna, and the noise generated from the second loop antenna interferes with the non-contact communication of the first loop antenna.
　本発明は、複数の通信アンテナを用いて同時に好適に非接触通信を行うことができるアンテナモジュール、電子機器及び非接触通信方法を提供することにある。 The present invention is to provide an antenna module, an electronic device, and a non-contact communication method capable of preferably simultaneously performing non-contact communication using a plurality of communication antennas.
　上記課題を解決するために、本発明の一態様のアンテナモジュールは、略同心状に配置された複数の通信アンテナを備えている。複数の通信アンテナは、アンテナ本体と、一対の端子部を有している。複数の通信アンテナの各々において、一対の端子部の少なくとも一方の端子部にデジタル信号が入力され、アンテナ本体を通って他方の端子部から出力されるようになっている。一対の端子部は、互いに間隔をあけて隣り合う内側端を有している。複数の通信アンテナは、少なくとも第１通信アンテナ及び第２通信アンテナを含む。第２通信アンテナが、第１通信アンテナの外側に当該第１通信アンテナに対して間隔をあけて配置されている。第１通信アンテナの中心から第１通信アンテナの一対の端子部の内側端の少なくとも一部を通る仮想の一対の第１半直線の間の領域を第１仮想領域とし、第１通信アンテナの中心又は第２通信アンテナの中心から第２通信アンテナの一対の端子部の内側端の少なくとも一部を通る仮想の一対の第２半直線の間の領域を第２仮想領域とした場合、第１仮想領域と第２仮想領域とが平面視において互いに重ならないように第１通信アンテナの一対の端子部及び第２通信アンテナの一対の端子部が配置されている。 In order to solve the above problems, the antenna module of one aspect of the present invention includes a plurality of communication antennas arranged substantially concentrically. The plurality of communication antennas have an antenna body and a pair of terminal portions. In each of the plurality of communication antennas, a digital signal is input to at least one terminal portion of the pair of terminal portions, and is output from the other terminal portion through the antenna body. The pair of terminals have inner ends that are spaced apart from each other and adjacent to each other. The plurality of communication antennas include at least a first communication antenna and a second communication antenna. The second communication antenna is arranged outside the first communication antenna at intervals from the first communication antenna. The area between the center of the first communication antenna and the pair of virtual first half straight lines passing through at least a part of the inner ends of the pair of terminals of the first communication antenna is defined as the first virtual area, and the center of the first communication antenna. Alternatively, when the area between the center of the second communication antenna and the pair of virtual second half lines passing through at least a part of the inner ends of the pair of terminals of the second communication antenna is defined as the second virtual area, the first virtual area is used. A pair of terminal portions of the first communication antenna and a pair of terminal portions of the second communication antenna are arranged so that the region and the second virtual region do not overlap each other in a plan view.
　一般的に、通信アンテナの端子部は、デジタル信号が入力されるため、当該端子部から反射によるノイズが発生し易い。しかし、上記態様のアンテナモジュールによる場合、第１仮想領域と第２仮想領域とが平面視において互いに重ならないように、第１通信アンテナの端子部が第２通信アンテナの端子部から離れて配置されているので、第１通信アンテナ及び第２通信アンテナを用いて同時に非接触通信を行う際に、第１通信アンテナの端子部から発生したノイズが第２通信アンテナの端子部と相手の第２方通信アンテナとの非接触通信に影響を与えたり、第２通信アンテナの端子部から発生したノイズが、第１通信アンテナの端子部と相手方の第１通信アンテナとの非接触通信に影響を与えたりする可能性が低減される。そのため、少なくとも第１通信アンテナと第２通信アンテナを用いて同時に非接触通信を好適に行うことができる。 In general, since a digital signal is input to the terminal portion of the communication antenna, noise due to reflection is likely to be generated from the terminal portion. However, in the case of the antenna module of the above aspect, the terminal portion of the first communication antenna is arranged apart from the terminal portion of the second communication antenna so that the first virtual area and the second virtual area do not overlap each other in the plan view. Therefore, when non-contact communication is performed simultaneously using the first communication antenna and the second communication antenna, the noise generated from the terminal part of the first communication antenna is generated from the terminal part of the second communication antenna and the second side of the other party. It affects the non-contact communication with the communication antenna, and the noise generated from the terminal part of the second communication antenna affects the non-contact communication between the terminal part of the first communication antenna and the first communication antenna of the other party. The possibility of doing so is reduced. Therefore, non-contact communication can be preferably performed at the same time by using at least the first communication antenna and the second communication antenna.
　一対の端子部は、内側端の反対側の外側端を更に有する構成とすることが可能である。第１通信アンテナの中心から第１通信アンテナの一対の端子部の外側端の少なくとも一部を通って放射状に延びる仮想の一対の第３半直線の間の領域を第３仮想領域とし、第１通信アンテナの中心又は第２通信アンテナの中心から第２通信アンテナの一対の端子部の外側端の少なくとも一部を通って延びる仮想の一対の第４半直線の間の領域を第４仮想領域とした場合、第３仮想領域と第４仮想領域とが平面視において互いに重ならないように、第１通信アンテナの一対の端子部及び第２通信アンテナの一対の端子部が配置された構成とすることが可能である。 The pair of terminal portions can be configured to further have an outer end on the opposite side of the inner end. The region between the center of the first communication antenna and the pair of virtual third half lines extending radially through at least a part of the outer ends of the pair of terminals of the first communication antenna is defined as the third virtual region, and the first The area between the center of the communication antenna or the center of the second communication antenna and the virtual pair of fourth half lines extending through at least a part of the outer ends of the pair of terminals of the second communication antenna is referred to as the fourth virtual area. In this case, a pair of terminal portions of the first communication antenna and a pair of terminal portions of the second communication antenna shall be arranged so that the third virtual area and the fourth virtual area do not overlap each other in a plan view. Is possible.
　このような態様のアンテナモジュールによる場合、第３仮想領域と第４仮想領域とが平面視において互いに重ならないように、第１通信アンテナの一対の端子部が第２通信アンテナの一対の端子部から更に離れて配置されているので、第１通信アンテナ及び第２通信アンテナを用いて同時に非接触通信を行う際に、第１通信アンテナの端子部から発生したノイズが第２通信アンテナの端子部と相手の第２方通信アンテナとの非接触通信に影響を与えたり、第２通信アンテナの端子部から発生したノイズが、第１通信アンテナの端子部と相手方の第１通信アンテナとの非接触通信に影響を与えたりする可能性が更に低減される。 In the case of the antenna module of such an embodiment, the pair of terminal portions of the first communication antenna is connected to the pair of terminal portions of the second communication antenna so that the third virtual area and the fourth virtual area do not overlap each other in the plan view. Since they are arranged further apart, noise generated from the terminal portion of the first communication antenna is generated from the terminal portion of the second communication antenna when the first communication antenna and the second communication antenna are used for simultaneous non-contact communication. Non-contact communication with the other party's second communication antenna or noise generated from the terminal of the second communication antenna causes non-contact communication between the terminal of the first communication antenna and the other party's first communication antenna. The possibility of affecting the antenna is further reduced.
　第１通信アンテナ及び第２通信アンテナの一対の端子部のうちの少なくとも一方の端子部にデジタル信号が入力されているときにおいて、第１通信アンテナの一対の端子部の電界強度が、第１通信アンテナのアンテナ本体の電界強度よりも強く、且つ、第２通信アンテナの一対の端子部の電界強度が、第２通信アンテナのアンテナ本体の電界強度よりも強くなっていても良い。 When a digital signal is input to at least one of the pair of terminals of the first communication antenna and the second communication antenna, the electric field strength of the pair of terminals of the first communication antenna is the first communication. The electric field strength of the pair of terminals of the second communication antenna may be stronger than the electric field strength of the antenna body of the antenna, and may be stronger than the electric field strength of the antenna body of the second communication antenna.
　第１通信アンテナ及び第２通信アンテナの一対の端子部のうちの少なくとも一方の端子部にデジタル信号が入力されているときにおいて、第１通信アンテナの一方の端子部の電界強度が、第１通信アンテナの他方の端子部の電界強度よりも強く、且つ、第２通信アンテナの一方の端子部の電界強度が、第２通信アンテナの他方の端子部の電界強度よりも強くなっていても良い。 When a digital signal is input to at least one of the pair of terminals of the first communication antenna and the second communication antenna, the electric field strength of one terminal of the first communication antenna is the first communication. The electric field strength of one terminal portion of the second communication antenna may be stronger than the electric field strength of the other terminal portion of the antenna, and may be stronger than the electric field strength of the other terminal portion of the second communication antenna.
　第２通信アンテナの電気長を第１通信アンテナの電気長よりも長くすることが可能である。この場合、第２通信アンテナに入力されるデジタル信号の伝送速度は、第１通信アンテナに入力されるデジタル信号の伝送速度よりも遅くすることが可能である。通信アンテナの全長が長くなり、その面積が増大すると、当該通信アンテナの電気長が長くなるため、当該通信アンテナで伝送速度の速いデジタル信号を伝送することが困難になる。そのため、電気長の長い第２通信アンテナに伝送速度の遅いデジタル信号を伝送させる一方で、電気長の短い第１通信アンテナに伝送速度の速いデジタル信号を伝送させることによって、同時に異なる通信速度の非接触通信を好適に行うことができる。 It is possible to make the electric length of the second communication antenna longer than the electric length of the first communication antenna. In this case, the transmission speed of the digital signal input to the second communication antenna can be slower than the transmission speed of the digital signal input to the first communication antenna. When the total length of the communication antenna is increased and the area is increased, the electric length of the communication antenna is increased, so that it becomes difficult for the communication antenna to transmit a digital signal having a high transmission speed. Therefore, by transmitting a digital signal having a slow transmission speed to the second communication antenna having a long electric length and transmitting a digital signal having a high transmission speed to a first communication antenna having a short electric length, different communication speeds are simultaneously generated. Contact communication can be preferably performed.
　第１通信アンテナの幅寸法を、第２通信アンテナの幅寸法よりも大きくすることが可能である。第１通信アンテナの幅寸法が大きくなり、第１通信アンテナの面積が増大すると、第１通信アンテナの電気長を長くすることができる。これにより、第１通信アンテナの電気長を、第２通信アンテナの電気長と略同じ又は近づけることができる。 It is possible to make the width dimension of the first communication antenna larger than the width dimension of the second communication antenna. When the width dimension of the first communication antenna is increased and the area of the first communication antenna is increased, the electric length of the first communication antenna can be increased. As a result, the electric length of the first communication antenna can be substantially the same as or close to the electric length of the second communication antenna.
　上記何れかの態様のアンテナモジュールは、第１通信アンテナと第２通信アンテナとの間に配置されたグランド導体を更に備えた構成とすることが可能である。このような態様のアンテナモジュールによる場合、グランド導体によって、第１通信アンテナに伝送されるデジタル信号と、第２通信アンテナに伝送されるデジタル信号とがクロストークする可能性が低減されるので、第１通信アンテナと第２通信アンテナとで同時に非接触通信をより好適に行うことができる。 The antenna module of any of the above aspects can be configured to further include a ground conductor arranged between the first communication antenna and the second communication antenna. In the case of the antenna module of such a mode, the ground conductor reduces the possibility of crosstalk between the digital signal transmitted to the first communication antenna and the digital signal transmitted to the second communication antenna. Non-contact communication can be more preferably performed simultaneously with the first communication antenna and the second communication antenna.
　上記何れかの態様のアンテナモジュールは、絶縁性を有する基体を更に備えた構成とすることが可能である。基体上には、上記何れかの態様の複数の通信アンテナが略同心状に設けられた構成とすることが可能である。 The antenna module of any of the above embodiments can be configured to further include an insulating substrate. It is possible to have a configuration in which a plurality of communication antennas of any of the above embodiments are provided substantially concentrically on the substrate.
　第１通信アンテナのアンテナ本体は、一部が破断した略環状とすることが可能である。この場合、第１通信アンテナの一対の端子部は、第１通信アンテナのアンテナ本体の両端部とすることが可能である。第２通信アンテナのアンテナ本体は、一部が破断した略環状とすることが可能である。この場合、第２通信アンテナの一対の端子部は、第２通信アンテナのアンテナ本体の両端部とすることが可能である。 The antenna body of the first communication antenna can be formed into a substantially annular shape with a part broken. In this case, the pair of terminal portions of the first communication antenna can be both ends of the antenna body of the first communication antenna. The antenna body of the second communication antenna can have a substantially annular shape with a part broken. In this case, the pair of terminal portions of the second communication antenna can be both ends of the antenna body of the second communication antenna.
　上記何れかの態様のアンテナモジュールは、第１送信部及び第２送信部を更に備えた構成とすることが可能である。第１送信部は、第１通信アンテナの一対の端子部の少なくとも一方に対してデジタル信号を送信可能な構成とすることが可能である。第２送信部は、第２通信アンテナの一対の端子部の少なくとも一方に対してデジタル信号を送信可能な構成とすることが可能である。 The antenna module of any of the above aspects can be configured to further include a first transmitter and a second transmitter. The first transmission unit can be configured to be capable of transmitting a digital signal to at least one of the pair of terminal units of the first communication antenna. The second transmission unit can be configured to be capable of transmitting a digital signal to at least one of the pair of terminal units of the second communication antenna.
　本発明の一態様の非接触通信装置は、第１アンテナモジュールと、第１アンテナモジュールに回転自在に支持された第２アンテナモジュールとを備えている。第１アンテナモジュール及び第２アンテナモジュールが上記何れかの態様のアンテナモジュールとすることが可能である。第１アンテナモジュールの第１通信アンテナと、第２アンテナモジュールの第１通信アンテナとが、第２アンテナモジュールの回転軸の軸方向において並ぶように配置されており、且つ、第１アンテナモジュールの第２通信アンテナと、第２アンテナモジュールの第２通信アンテナとが、軸方向において並ぶように配置されている。なお、第２アンテナモジュールは、第１アンテナモジュールに対して回転自在に支持されている必要はなく、非接触通信時に互いに対向する構成であれば良い。 The non-contact communication device of one aspect of the present invention includes a first antenna module and a second antenna module rotatably supported by the first antenna module. The first antenna module and the second antenna module can be the antenna module of any of the above aspects. The first communication antenna of the first antenna module and the first communication antenna of the second antenna module are arranged so as to be aligned in the axial direction of the rotation axis of the second antenna module, and the first antenna module is the first. The two communication antennas and the second communication antenna of the second antenna module are arranged so as to be aligned in the axial direction. The second antenna module does not need to be rotatably supported by the first antenna module, and may be configured to face each other during non-contact communication.
　本発明の一態様の非接触通信方法は、上記何れかの態様のアンテナモジュールの第１通信アンテナの一対の端子部に対してデジタル信号を入力すると共に、上記何れかの態様のアンテナモジュールの第２通信アンテナの一対の端子部に対してデジタル信号を入力することを含む。 In the non-contact communication method of one aspect of the present invention, a digital signal is input to a pair of terminals of the first communication antenna of the antenna module of any of the above aspects, and the antenna module of any of the above aspects is described. 2 Includes inputting a digital signal to a pair of terminals of a communication antenna.

The distance is input from the unit 222a, passes through the first antenna main body 210a, and reaches the first terminal unit 221a, or each of these distances. The electrical length of the second communication antenna 200a is the distance from the first terminal portion 221a to the second terminal portion 222a through the second antenna main body 210a during transmission, and the second digital signal during transmission. It is the distance input from the terminal portion 222a, passing through the second antenna main body 210a to reach the first terminal portion 221a, or the distances of each of them. The electrical length of the second communication antenna 200a is because the second antenna main body 210a is arranged outside the first antenna main body 210a, and the area of the second antenna main body 210a is larger than the area of the first antenna main body 210a. , It becomes longer than the electric length of the first communication antenna 200a.
　第１アンテナ本体２１０ａの幅寸法Ｗは、第２アンテナ本体２１０ａの幅寸法Ｗよりも大きくすることが可能である。例えば、第１アンテナ本体２１０ａの幅寸法Ｗを０．５～１．０ｍｍとし、第２アンテナ本体２１０ａの幅寸法Ｗを１．０～１．５ｍｍとすることが可能である。第１アンテナ本体２１０ａの幅寸法Ｗを第２アンテナ本体２１０ａの幅寸法Ｗよりも大きくすれば、第１アンテナ本体２１０ａの面積が増大し、その結果として、第１通信アンテナ２００ａの電気長が増大する。これを利用して、第１通信アンテナ２００ａの電気長が第２通信アンテナ２００ａの電気長と略同じになる又は近くなるように、第１アンテナ本体２１０ａの幅寸法Ｗを第２アンテナ本体２１０ａの幅寸法Ｗよりも大きくしても良い。なお、第１通信アンテナ２００ａの電気長が第２通信アンテナ２００ａの電気長と略同じになる又は近くなるように、第１アンテナ本体２１０ａの幅寸法Ｗを増大させる手段以外の手段で、第１アンテナ本体２１０ａの面積を増大させても構わない。 The width dimension W of the first antenna main body 210a can be made larger than the width dimension W of the second antenna main body 210a. For example, the width dimension W of the first antenna main body 210a can be set to 0.5 to 1.0 mm, and the width dimension W of the second antenna main body 210a can be set to 1.0 to 1.5 mm. If the width dimension W of the first antenna main body 210a is made larger than the width dimension W of the second antenna main body 210a, the area of the first antenna main body 210a increases, and as a result, the electric length of the first communication antenna 200a increases. To do. Utilizing this, the width dimension W of the first antenna main body 210a is set to be substantially the same as or close to the electric length of the second communication antenna 200a of the second antenna main body 210a. It may be larger than the width dimension W. The first means other than the means for increasing the width dimension W of the first antenna main body 210a so that the electric length of the first communication antenna 200a becomes substantially the same as or close to the electric length of the second communication antenna 200a. The area of the antenna body 210a may be increased.

Further, the width dimension W of the first antenna main body 210a may be smaller than the width dimension W of the second antenna main body 210a, or the width dimension W of both may be the same.

Each transmission unit 410a is composed of a logic circuit such as an IC capable of transmitting a digital signal to at least one of the terminal units 221a and 222a of the corresponding communication antenna 200a, or software processed by a processor or the like. The digital signal that can be transmitted by each transmission unit 410a can be a square wave differential signal having a wide band frequency component or a square wave single-ended signal having a wide band frequency component. This digital signal contains a high frequency component of several hundred MHz or more, and more preferably contains a high frequency component of 1 GHz to 5 GHz, but the digital signal is not limited thereto. The transmission speed of the differential signal can be 500 kbps to 1.5 Gbps, but is not limited to this.

In this case, in each communication antenna 200a, a single-ended signal is input from one terminal portion, passes through the antenna main body 210a, and is output from the other terminal portion. When a single-ended signal is input to one terminal of the communication antenna 200a, the electric field strength of one of the communication antennas 200a (terminals for input and output) is the antenna of the communication antenna 200a. It is stronger than the electric field strength of the main body 210a, and the electric field strength of one terminal part (terminal part for input) of the communication antenna 200a is higher than the electric field strength of the other terminal part (terminal part for output) of the communication antenna 200a.

　以上のようなモジュールＭ１は、以下の技術的特徴及び効果を奏する。
　技術的特徴及び効果１）
　モジュールＭ１の第１通信アンテナ２００ａとモジュールＭ２の第１通信アンテナ２００ｂとの間及びモジュールＭ１の第２通信アンテナ２００ａとモジュールＭ２の第２通信アンテナ２００ｂとの間で同時に非接触通信を好適に行うことができる。その理由は以下の通りである。 The module M1 as described above exhibits the following technical features and effects.
Technical features and effects 1)
Non-contact communication is preferably performed simultaneously between the first communication antenna 200a of the module M1 and the first communication antenna 200b of the module M2 and between the second communication antenna 200a of the module M1 and the second communication antenna 200b of the module M2. be able to. The reason is as follows.
　（ア）一般的に、通信アンテナの一対の端子部にディファレンシャル信号の正側信号、負側信号が入力される場合、通信アンテナの一対の端子部において、正側信号、負側信号の差動バランスが崩れる等して反射が生じ易く、反射によるノイズが発生し易い。
　しかし、モジュールＭ１において、第１、第２通信アンテナ２００ａが略同心円状に配置されているものの、上記第１仮想領域と上記第２仮想領域とがＺ方向側から見て（平面視において）互いに重ならないように又は上記第３仮想領域と上記第４仮想領域とがＺ方向側から見て（平面視において）互いに重ならないようにすることによって、第１通信アンテナ２００ａの第１端子部２２１ａ、２２２ａが第２通信アンテナ２００ａの第２端子部２２１ａ、２２２ａから離れて配置することができる。このため、第１通信アンテナ２００ａの第１端子部２２１ａ、２２２ａにディファレンシャル信号の正側信号、負側信号が入力されることによって、第１端子部２２１ａ及び／又は２２２ａから生じたノイズが、モジュールＭ１の第２通信アンテナ２００ａの第２端子部２２１ａ、２２２ａとモジュールＭ２の第２通信アンテナ２００ｂとの間の非接触通信に干渉したり、モジュールＭ１の第２通信アンテナ２００ａの第２端子部２２１ａ、２２２ａにディファレンシャル信号の正側信号、負側信号が入力されることによって、第２端子部２２１ａ及び／又は２２２ａから生じたノイズが、モジュールＭ１の第１通信アンテナ２００ａの第１端子部２２１ａ、２２２ａとモジュールＭ２の第１通信アンテナ２００ｂとの間の非接触通信に干渉したりする可能性が低減される。しかも、モジュールＭ１の第２通信アンテナ２００ａの第２端子部２２１ａ、２２２ａとモジュールＭ２の第２通信アンテナ２００ｂとの間は、上記の通り、電磁界結合が強い部分であるため、当該部分の非接触通信に対するノイズの干渉が低減されることによって、当該非接触通信を好適に行うことができ、モジュールＭ１の第１通信アンテナ２００ａの第１端子部２２１ａ、２２２ａとモジュールＭ２の第１通信アンテナ２００ｂとの間も、上記の通り、電磁界結合が強い部分であるため、当該部分の非接触通信に対するノイズの干渉が低減されることによって、当該非接触通信を好適に行うことができる。 (A) Generally, when the positive side signal and the negative side signal of the differential signal are input to the pair of terminal parts of the communication antenna, the differential between the positive side signal and the negative side signal is made in the pair of terminal parts of the communication antenna. Reflections are likely to occur due to imbalance, etc., and noise due to reflections is likely to occur.
However, in the module M1, although the first and second communication antennas 200a are arranged substantially concentrically, the first virtual area and the second virtual area are viewed from the Z direction side (in a plan view). The first terminal portion 221a of the first communication antenna 200a, by not overlapping or by preventing the third virtual area and the fourth virtual area from overlapping each other when viewed from the Z direction side (in a plan view), The 222a can be arranged away from the second terminal portions 221a and 222a of the second communication antenna 200a. Therefore, when the positive side signal and the negative side signal of the differential signal are input to the first terminal portions 221a and 222a of the first communication antenna 200a, the noise generated from the first terminal portion 221a and / or 222a is generated by the module. It interferes with non-contact communication between the second terminal portion 221a and 222a of the second communication antenna 200a of the M1 and the second communication antenna 200b of the module M2, or the second terminal portion 221a of the second communication antenna 200a of the module M1. When the positive side signal and the negative side signal of the differential signal are input to 222a, the noise generated from the second terminal part 221a and / or 222a is generated by the first terminal part 221a of the first communication antenna 200a of the module M1. The possibility of interfering with non-contact communication between the 222a and the first communication antenna 200b of the module M2 is reduced. Moreover, since the electromagnetic field coupling is strong between the second terminal portions 221a and 222a of the second communication antenna 200a of the module M1 and the second communication antenna 200b of the module M2 as described above, this portion is not present. By reducing the interference of noise with respect to the contact communication, the non-contact communication can be suitably performed, and the first terminal portions 221a and 222a of the first communication antenna 200a of the module M1 and the first communication antenna 200b of the module M2 can be performed. As described above, since the electromagnetic field coupling is strong, the non-contact communication can be preferably performed by reducing the interference of noise with respect to the non-contact communication of the portion.
　（イ）一般的に、通信アンテナの端子部にシングルエンド信号が入力される場合、端子部においてシングルエンド信号の反射が生じ易く、反射によるノイズが発生し易い。
　しかし、モジュールＭ１において、第１、第２通信アンテナ２００ａが略同心円状に配置されているものの、上記第１仮想領域と上記第２仮想領域とがＺ方向側から見て（平面視において）互いに重ならないように又は上記第３仮想領域と上記第４仮想領域とがＺ方向側から見て（平面視において）互いに重ならないようにすることによって、第１通信アンテナ２００ａの第１端子部２２１ａ、２２２ａが第２通信アンテナ２００ａの第２端子部２２１ａ、２２２ａから離れて配置することができる。このため、第１通信アンテナ２００ａの第１端子部２２１ａにシングルエンド信号が入力されることによって、第１通信アンテナ２００ａの第１端子部２２１ａから生じたノイズが、モジュールＭ１の第２通信アンテナ２００ａの第２端子部２２１ａ、２２２ａとモジュールＭ２の第２通信アンテナ２００ｂとの間の非接触通信に干渉したり、第２通信アンテナ２００ａの第１端子部２２１ａにシングルエンド信号が入力されることによって、第２端子部２２１ａから生じたノイズが、モジュールＭ１の第１通信アンテナ２００ａの第１端子部２２１ａ、２２２ａとモジュールＭ２の第１通信アンテナ２００ｂとの間の非接触通信に干渉したりする可能性が低減される。しかも、モジュールＭ１の第２通信アンテナ２００ａの第２端子部２２１ａとモジュールＭ２の第２通信アンテナ２００ｂとの間は、上記の通り、電磁界結合が強い部分であるため、当該部分の非接触通信に対するノイズの干渉が低減されることによって、当該非接触通信を好適に行うことができ、モジュールＭ１の第１通信アンテナ２００ａの第１端子部２２１ａとモジュールＭ２の第１通信アンテナ２００ｂとの間も、上記の通り、電磁界結合が強い部分であるため、当該部分の非接触通信に対するノイズの干渉が低減されることによって、当該非接触通信を好適に行うことができる。 (B) Generally, when a single-ended signal is input to the terminal portion of a communication antenna, the single-ended signal is likely to be reflected at the terminal portion, and noise due to the reflection is likely to occur.
However, in the module M1, although the first and second communication antennas 200a are arranged substantially concentrically, the first virtual area and the second virtual area are viewed from the Z direction side (in a plan view). The first terminal portion 221a of the first communication antenna 200a, by not overlapping or by preventing the third virtual area and the fourth virtual area from overlapping each other when viewed from the Z direction side (in a plan view), The 222a can be arranged away from the second terminal portions 221a and 222a of the second communication antenna 200a. Therefore, when the single-ended signal is input to the first terminal portion 221a of the first communication antenna 200a, the noise generated from the first terminal portion 221a of the first communication antenna 200a is generated by the second communication antenna 200a of the module M1. By interfering with non-contact communication between the second terminal portion 221a and 222a of the module M2 and the second communication antenna 200b of the module M2, or by inputting a single-ended signal to the first terminal portion 221a of the second communication antenna 200a. , Noise generated from the second terminal portion 221a may interfere with non-contact communication between the first terminal portions 221a and 222a of the first communication antenna 200a of the module M1 and the first communication antenna 200b of the module M2. The property is reduced. Moreover, since the electromagnetic field coupling is strong between the second terminal portion 221a of the second communication antenna 200a of the module M1 and the second communication antenna 200b of the module M2 as described above, non-contact communication of the portion is performed. By reducing the interference of noise with respect to the above, the non-contact communication can be suitably performed, and also between the first terminal portion 221a of the first communication antenna 200a of the module M1 and the first communication antenna 200b of the module M2. As described above, since the portion has a strong electromagnetic field coupling, the non-contact communication can be preferably performed by reducing the interference of noise with respect to the non-contact communication of the portion.
　（ウ）入力されるデジタル信号がディファレンシャル信号及びシングルエンド信号の何れの場合であっても、第３仮想領域と第４仮想領域とが互いに重ならない場合、第１仮想領域と第２仮想領域とのみが互いに重ならない場合に比べて、第１端子部２２１ａ、２２２ａが第２端子部２２１ａ、２２２ａからより遠くに離れるため、上記（ア）又は（イ）の技術的特徴が顕著になる。 (C) Regardless of whether the input digital signal is a differential signal or a single-ended signal, if the third virtual area and the fourth virtual area do not overlap each other, the first virtual area and the second virtual area Since the first terminal portions 221a and 222a are farther away from the second terminal portions 221a and 222a as compared with the case where only the terminals do not overlap each other, the technical features of (a) or (b) above become remarkable.
　（エ）第１通信アンテナ２００ａと第２通信アンテナ２００ａとの間にグランド導体３００ａが配置されている場合、第１通信アンテナ２００ａに伝送されるデジタル信号と、第２通信アンテナ２００ａに伝送されるデジタル信号とがクロストークする可能性が低減されるので、第１通信アンテナ２００ａと第２通信アンテナ２００ａとで同時に非接触通信を更により好適に行うことができる。 (D) When the ground conductor 300a is arranged between the first communication antenna 200a and the second communication antenna 200a, the digital signal transmitted to the first communication antenna 200a and the digital signal transmitted to the second communication antenna 200a are transmitted. Since the possibility of cross-talking with the digital signal is reduced, non-contact communication can be more preferably performed simultaneously between the first communication antenna 200a and the second communication antenna 200a.
　技術的特徴及び効果２）
　モジュールＭ１においては、第２通信アンテナ２００ａが第１通信アンテナ２００ａの外側に配置されており、第２通信アンテナ２００ａの面積が、第１通信アンテナ２００ａの面積よりも大きい場合、第２通信アンテナ２００ａの電気長が第１通信アンテナ２００ａの電気長よりも長くなる。この場合、第２送信部４１０ａにより送信されるデジタル信号の伝送速度を、第１送信部４１０ｂにより送信されるデジタル信号の伝送速度よりも遅くすることによって、第１通信アンテナ２００ａ及び第２通信アンテナ２００ａを用いて同時に異なる通信速度の非接触通信を好適に行うことができる。 Technical features and effects 2)
In the module M1, when the second communication antenna 200a is arranged outside the first communication antenna 200a and the area of the second communication antenna 200a is larger than the area of the first communication antenna 200a, the second communication antenna 200a The electric length of the first communication antenna 200a is longer than the electric length of the first communication antenna 200a. In this case, by making the transmission speed of the digital signal transmitted by the second transmission unit 410a slower than the transmission speed of the digital signal transmitted by the first transmission unit 410b, the first communication antenna 200a and the second communication antenna The 200a can preferably be used for non-contact communication at different communication speeds at the same time.
　技術的特徴及び効果３）
　第１通信アンテナ２００ａの幅寸法Ｗが、第２通信アンテナ２００ａの幅寸法Ｗよりも大きい場合、第１通信アンテナ２００ａの面積が増大することにより、第１通信アンテナ２００ａの電気長を第２通信アンテナ２００ａの電気長と略同じ又は近くすることができる。この場合、第１通信アンテナ２００ａ及び第２通信アンテナ２００ａを用いて同時に異なる通信速度の非接触通信を行っても良いし、同じ通信速度で非接触通信を行っても良い。 Technical features and effects 3)
When the width dimension W of the first communication antenna 200a is larger than the width dimension W of the second communication antenna 200a, the area of the first communication antenna 200a increases, so that the electric length of the first communication antenna 200a is changed to the second communication. It can be substantially the same as or close to the electrical length of the antenna 200a. In this case, the first communication antenna 200a and the second communication antenna 200a may be used for non-contact communication at different communication speeds at the same time, or non-contact communication may be performed at the same communication speed.
