JP 2004-362131 A

しかしながら、図６に示す無線通信システムのように、アンテナ１１２が無線通信装置１０２に内蔵されていると、無線通信装置１０２は小型であるため、アンテナ１１２も小型になり、アンテナ１１２の受信特性が低下するという問題があった。   However, as in the wireless communication system illustrated in FIG. 6, when the antenna 112 is incorporated in the wireless communication device 102, the wireless communication device 102 is small, and thus the antenna 112 is also small. There was a problem of lowering.

また、図７に示す無線通信システムのように、ＬＡＮ通信等の無線通信時にしかアンテナ２１４は使用されないにもかかわらず、アンテナ２１４が情報処理端末２０３に内蔵されていると、情報処理端末２０３はアンテナ２１４の重量分重くなるという問題があった。   In addition, as in the wireless communication system illustrated in FIG. 7, when the antenna 214 is incorporated in the information processing terminal 203 even though the antenna 214 is used only during wireless communication such as LAN communication, the information processing terminal 203 is There is a problem that the weight of the antenna 214 increases.

本発明は以上のような問題を解決し、アンテナの受信特性を向上させることを目的とするものである。   An object of the present invention is to solve the above problems and to improve the reception characteristics of an antenna.

上記目的を達成するために、本発明の無線通信装置用アダプタは、第１アンテナと、この第１アンテナと電気的に接続されるとともに、無線通信装置が無線通信装置用アダプタに挿入接続された場合、無線通信装置の無線回路と電気的に接続される第１端子とを有する。   In order to achieve the above object, an adapter for a wireless communication device according to the present invention is electrically connected to a first antenna and the first antenna, and the wireless communication device is inserted and connected to the adapter for a wireless communication device. A first terminal electrically connected to a wireless circuit of the wireless communication device.

従って、本発明の無線通信装置用アダプタは、無線通信装置が挿入接続されるために一般的に無線通信装置よりも大きなサイズであるので、第１アンテナを、従来の無線通信装置内蔵型のアンテナよりも大きくすることができる。その結果、アンテナの受信特性を向上させることができる。また、第１アンテナは、情報処理端末に搭載されていないので、情報処理端末を軽量化することができる。   Accordingly, since the adapter for a wireless communication device of the present invention is generally larger in size than the wireless communication device because the wireless communication device is inserted and connected, the first antenna is replaced with a conventional antenna with a built-in wireless communication device. Can be larger. As a result, the reception characteristics of the antenna can be improved. Moreover, since the first antenna is not mounted on the information processing terminal, the information processing terminal can be reduced in weight.

さらに、無線通信装置が無線通信装置用アダプタに挿入接続された場合、上方向から見て、無線通信装置用アダプタの第１信号線と無線通信装置の第２信号線とは重ならない。この構成により、第１信号線と第２信号線との距離が大きくなるので、第１信号線を通る高周波信号と第２信号線を通る高周波信号とが干渉しあうことを抑制することができる。従って、第１アンテナで受信した高周波信号を、第１アンテナから無線回路まで効率よく伝送させることができる。   Furthermore, when the wireless communication device is inserted and connected to the wireless communication device adapter, the first signal line of the wireless communication device adapter and the second signal line of the wireless communication device do not overlap when viewed from above. With this configuration, since the distance between the first signal line and the second signal line is increased, it is possible to suppress interference between the high-frequency signal passing through the first signal line and the high-frequency signal passing through the second signal line. . Therefore, a high frequency signal received by the first antenna can be efficiently transmitted from the first antenna to the radio circuit.

また、無線通信装置が無線通信装置用アダプタに挿入接続された場合、本発明における無線通信装置用アダプタの第１アンテナは、無線通信装置より上側に位置する。無線通信装置用アダプタが上向きに挿入接続されるようにノートパソコンに無線通信装置用アダプタのスロットが設けられている場合が多い。このようなノートパソコンが載置されている机が金属などの導電性部材からなる場合、この構成により、机と第１アンテナとの距離が大きくなるので、第１アンテナの受信特性の低下を抑制することができる。   When the wireless communication device is inserted and connected to the wireless communication device adapter, the first antenna of the wireless communication device adapter in the present invention is located above the wireless communication device. In many cases, a notebook computer is provided with a slot for a wireless communication device adapter so that the wireless communication device adapter is inserted and connected upward. When the desk on which such a notebook computer is placed is made of a conductive member such as metal, this configuration increases the distance between the desk and the first antenna, thereby suppressing a decrease in reception characteristics of the first antenna. can do.

さらにまた、本発明の無線通信装置は、第２アンテナと、無線通信装置が無線通信装置用アダプタに挿入接続された場合、無線通信装置用アダプタが有する第１アンテナと電気的に接続される第２端子と、第１アンテナから第２端子を介して供給される信号と第２アンテナから供給される信号とをダイバーシティ方式で受信する無線回路とを有する。この構成により、無線通信装置における受信特性を向上させることができる。   Furthermore, the wireless communication device of the present invention is configured such that when the second antenna and the wireless communication device are inserted and connected to the adapter for the wireless communication device, the first antenna electrically connected to the first antenna included in the adapter for the wireless communication device. And a radio circuit that receives a signal supplied from the first antenna via the second terminal and a signal supplied from the second antenna in a diversity manner. With this configuration, it is possible to improve reception characteristics in the wireless communication device.

And a radio circuit that receives a signal supplied from the third antenna via the second terminal through a diversity system. With this configuration, it is possible to improve reception characteristics in the wireless communication device.

(実施の形態１)
以下、本発明における無線通信装置用アダプタおよび無線通信装置について、図１を参照しながら説明する。 (Embodiment 1)
Hereinafter, an adapter for a wireless communication device and a wireless communication device according to the present invention will be described with reference to FIG.

図１に示すように、無線通信装置用アダプタ１には、無線通信装置２が挿入接続される。また、情報処理端末３には、無線通信装置用アダプタ１が挿入接続される。   As shown in FIG. 1, a wireless communication device 2 is inserted and connected to the wireless communication device adapter 1. Further, the wireless communication device adapter 1 is inserted and connected to the information processing terminal 3.

無線通信装置用アダプタ１は、例えば、ｍｉｎｉＳＤＩＯ無線通信カ−ドが挿入接続されるカード型アダプタである。無線通信装置用アダプタ１は、第１アンテナ４を有する。また、無線通信装置用アダプタ１は、無線通信装置２が無線通信装置用アダプタ１に挿入接続された場合に、無線通信装置２と電気的に接続される第１端子５を有する。さらに、第１アンテナ４と第１端子５とは、無線通信装置用アダプタ１の第１信号線６によって電気的に接続されている。なお、無線通信装置用アダプタ１は、情報処理端末３に信号を送受信するための端子（図示せず）を有する。   The wireless communication device adapter 1 is, for example, a card type adapter into which a miniSDIO wireless communication card is inserted and connected. The wireless communication device adapter 1 has a first antenna 4. The wireless communication device adapter 1 includes a first terminal 5 that is electrically connected to the wireless communication device 2 when the wireless communication device 2 is inserted and connected to the wireless communication device adapter 1. Furthermore, the first antenna 4 and the first terminal 5 are electrically connected by the first signal line 6 of the adapter 1 for the wireless communication device. The wireless communication device adapter 1 has a terminal (not shown) for transmitting and receiving signals to and from the information processing terminal 3.

無線通信装置２は、例えば、ｍｉｎｉＳＤＩＯ無線通信カ−ドである。無線通信装置２は、無線回路７と、無線通信装置２が無線通信装置用アダプタ１に挿入接続された場合に、第１端子５と接続される第２端子８とを有する。また、無線回路７と第２端子８とは、無線通信装置２の第２信号線９によって電気的に接続されている。   The wireless communication device 2 is, for example, a miniSDIO wireless communication card. The wireless communication device 2 includes a wireless circuit 7 and a second terminal 8 connected to the first terminal 5 when the wireless communication device 2 is inserted and connected to the wireless communication device adapter 1. The wireless circuit 7 and the second terminal 8 are electrically connected by the second signal line 9 of the wireless communication device 2.

情報処理端末３は、例えば、携帯電話やノートパソコンなどの情報処理装置である。情報処理端末３は、無線通信装置用アダプタ１を挿入接続するためのスロット１０を有する。なお、情報処理端末３は、無線通信装置用アダプタ１に信号を送受信するための端子（図示せず）を有する。   The information processing terminal 3 is an information processing apparatus such as a mobile phone or a notebook computer. The information processing terminal 3 has a slot 10 for inserting and connecting the wireless communication device adapter 1. The information processing terminal 3 has a terminal (not shown) for transmitting and receiving signals to the wireless communication device adapter 1.

無線通信装置２が無線通信装置用アダプタ１に挿入接続されると、無線通信装置用アダプタ１の第１端子５と無線通信装置２の第２端子８とは電気的に接続され、第１アンテナ４と無線回路７とが電気的に接続される。次に、無線通信装置２が無線通信装置用アダプタ１に挿入接続されたまま、無線通信装置用アダプタ１が情報処理端末３のスロット１０に挿入接続される。この状態で、第１アンテナ４は、電波を受信し、この電波に含まれている高周波信号を無線回路７に供給する。そして、無線回路７は、この高周波信号を処理する。その結果、ユーザは、情報処理端末３を使って、ＬＡＮ通信等の無線通信を行う事ができる。   When the wireless communication device 2 is inserted and connected to the wireless communication device adapter 1, the first terminal 5 of the wireless communication device adapter 1 and the second terminal 8 of the wireless communication device 2 are electrically connected, and the first antenna 4 and the radio circuit 7 are electrically connected. Next, the wireless communication device adapter 1 is inserted and connected to the slot 10 of the information processing terminal 3 while the wireless communication device 2 is inserted and connected to the wireless communication device adapter 1. In this state, the first antenna 4 receives a radio wave and supplies a high frequency signal included in the radio wave to the radio circuit 7. Then, the radio circuit 7 processes this high frequency signal. As a result, the user can perform wireless communication such as LAN communication using the information processing terminal 3.

従って、無線通信装置用アダプタ１は、無線通信装置２が挿入接続されるために一般的に無線通信装置２よりも大きなサイズであるので、第１アンテナ４を、従来の無線通信装置２内蔵型のアンテナよりも大きくすることができる。その結果、アンテナの受信特性を向上させることができる。また、第１アンテナ４は、情報処理端末３に搭載されていないので、情報処理端末３を軽量化することができる。   Therefore, since the wireless communication device adapter 1 is generally larger in size than the wireless communication device 2 because the wireless communication device 2 is inserted and connected, the first antenna 4 is connected to the conventional wireless communication device 2 built-in type. Can be larger than the antenna. As a result, the reception characteristics of the antenna can be improved. Moreover, since the 1st antenna 4 is not mounted in the information processing terminal 3, the information processing terminal 3 can be reduced in weight.

次に、無線通信装置用アダプタ１について図２を参照しながら詳述する。   Next, the wireless communication device adapter 1 will be described in detail with reference to FIG.

第１アンテナ４は、チップ形状を有する積層セラミックからなる。これにより、第１アンテナ４の実装自由度を高めることができる。また、第１アンテナ４は金属片であっても構わない。これにより、第１アンテナ４の放射効率を高めることができる。なお、第１アンテナ４は空芯コイルであっても構わない。また、第１アンテナ４は受信専用アンテナであっても構わないし、送受信用アンテナであっても構わない。   The first antenna 4 is made of a multilayer ceramic having a chip shape. Thereby, the mounting freedom degree of the 1st antenna 4 can be raised. The first antenna 4 may be a metal piece. Thereby, the radiation efficiency of the 1st antenna 4 can be improved. The first antenna 4 may be an air-core coil. The first antenna 4 may be a reception-only antenna or a transmission / reception antenna.

また、無線通信装置２が無線通信装置用アダプタ１に挿入接続された場合、無線通信装置２が有する無線回路７等の電子部品と第１アンテナ４とは、無線通信装置用アダプタ１を上方向から見て重ならないことが望ましい。この構成により、無線通信装置２が有する電子部品と第１アンテナ４との距離が大きくなるので、第１アンテナ４の放射効率の低下を抑制することができる。なお、無線通信装置用アダプタ１を上方向から見るとは、図２に示すように、無線通信装置用アダプタ１を正面から見ることを示す。   When the wireless communication device 2 is inserted and connected to the wireless communication device adapter 1, the electronic components such as the wireless circuit 7 included in the wireless communication device 2 and the first antenna 4 are directed upward with the wireless communication device adapter 1. It is desirable that they do not overlap with each other. With this configuration, the distance between the electronic component of the wireless communication device 2 and the first antenna 4 is increased, so that a decrease in the radiation efficiency of the first antenna 4 can be suppressed. Note that viewing the wireless communication device adapter 1 from above refers to viewing the wireless communication device adapter 1 from the front as shown in FIG.

また、無線通信装置２が無線通信装置用アダプタ１に挿入接続された場合、無線通信装置用アダプタ１の第１アンテナ４は無線通信装置２より上側に位置することが望ましい。なお、ここでいう上の方向は、図２の無線通信装置用アダプタ１において、紙面の裏面から表面に向かう方向を指す。無線通信装置用アダプタ１が上向きに挿入接続されるようにノートパソコンに無線通信装置用アダプタ１のスロット１０が設けられている場合が多い。このようなノートパソコンが載置されている机が金属などの導電性部材からなる場合、この構成により、机と第１アンテナ４との距離が大きくなるので、第１アンテナ４の受信特性の低下を抑制することができる。   When the wireless communication device 2 is inserted and connected to the wireless communication device adapter 1, the first antenna 4 of the wireless communication device adapter 1 is preferably located above the wireless communication device 2. In addition, the upper direction here refers to the direction which goes to the surface from the back surface of a paper surface in the adapter 1 for radio | wireless communication apparatuses of FIG. In many cases, the slot 10 of the wireless communication device adapter 1 is provided in the notebook personal computer so that the wireless communication device adapter 1 is inserted and connected upward. When the desk on which such a notebook computer is placed is made of a conductive member such as metal, the distance between the desk and the first antenna 4 is increased by this configuration, so that the reception characteristics of the first antenna 4 are deteriorated. Can be suppressed.

また、無線通信装置用アダプタ１は、情報処理端末３と接続するための、例えば、ａ−１からａ−９までの９個の端子を有する。また、無線通信装置用アダプタ１は、無線通信装置２と接続するための、例えば、Ａ−１からＡ−１１までの１１個の端子を有する。そして、ａ−１とＡ−１、ａ−２とＡ−２、・・・、及びａ−９とＡ−９は各々電気的に接続されている。   The wireless communication device adapter 1 has, for example, nine terminals a-1 to a-9 for connection with the information processing terminal 3. The wireless communication device adapter 1 has, for example, 11 terminals A-1 to A-11 for connection to the wireless communication device 2. And a-1 and A-1, a-2 and A-2, ..., and a-9 and A-9 are each electrically connected.

Ａ−１からＡ−９までの端子の信号は、規格で定められている。例えばＡ−４は、接地端子である。そして、Ａ−１０およびＡ−１１の端子は、任意の端子に設定する事ができる拡張端子である。このＡ−１１の端子が、第１アンテナ４と第１信号線６を介して電気的に接続されている第１端子５である。また、Ａ−１０の端子を接地端子と設定することにより、第１端子５の両隣の端子が接地端子となる。その結果、第１端子５を通る高周波信号が、他の端子を通る信号に干渉されることを抑制することができる。従って、無線通信の品質の劣化を防ぐことができる。   The signals at the terminals A-1 to A-9 are defined by the standard. For example, A-4 is a ground terminal. The terminals A-10 and A-11 are extension terminals that can be set to arbitrary terminals. The terminal A-11 is the first terminal 5 that is electrically connected to the first antenna 4 via the first signal line 6. Further, by setting the terminal A-10 as a ground terminal, both terminals adjacent to the first terminal 5 become ground terminals. As a result, it is possible to suppress interference of a high-frequency signal passing through the first terminal 5 with a signal passing through another terminal. Therefore, it is possible to prevent deterioration of the quality of wireless communication.

また、第１信号線６は、例えば、同軸ケーブルまたはマイクロストリップラインまたはストリップライン線路で構成されている。   Further, the first signal line 6 is constituted by, for example, a coaxial cable, a microstrip line, or a strip line line.

次に、無線通信装置２について図３を参照しながら詳述する。   Next, the wireless communication device 2 will be described in detail with reference to FIG.

無線通信装置２は、無線回路７と、無線回路７からの信号を処理する処理回路１１とを有する。無線回路７は、第１アンテナ４で受信した信号の中から所望の周波数帯域の信号を取り出し、取り出した信号を中間周波信号に変換し、この中間周波信号を処理回路１１に出力する。処理回路１１は、無線回路７からの中間周波信号を復調することにより復調データ信号を生成し、この復調データ信号を、無線通信装置用アダプタ１を介して、情報処理端末３に出力する。   The wireless communication device 2 includes a wireless circuit 7 and a processing circuit 11 that processes a signal from the wireless circuit 7. The radio circuit 7 extracts a signal in a desired frequency band from the signals received by the first antenna 4, converts the extracted signal into an intermediate frequency signal, and outputs the intermediate frequency signal to the processing circuit 11. The processing circuit 11 generates a demodulated data signal by demodulating the intermediate frequency signal from the radio circuit 7 and outputs the demodulated data signal to the information processing terminal 3 via the adapter 1 for the radio communication device.

また、無線通信装置２は、Ｐｃ−１からＰｃ−１１までの１１個の端子を有する。そして、無線通信装置２が無線通信装置用アダプタ１に挿入接続された場合に、これらＰｃ−１からＰｃ−１１までの端子は、無線通信装置用アダプタ１におけるＡ−１からＡ−１１までの端子と電気的に各々接続される。これらの端子の中で、Ｐｃ−１１の端子が、無線回路７と第２信号線９を介して電気的に接続されている第２端子８である。   Further, the wireless communication device 2 has 11 terminals from Pc-1 to Pc-11. When the wireless communication device 2 is inserted and connected to the wireless communication device adapter 1, the terminals from Pc-1 to Pc-11 are connected to the wireless communication device adapter 1 from A-1 to A-11. Each is electrically connected to a terminal. Among these terminals, the terminal Pc-11 is the second terminal 8 that is electrically connected to the wireless circuit 7 via the second signal line 9.

第２信号線９は、例えば、同軸ケーブルまたはマイクロストリップラインまたはストリップライン線路で構成されている。なお、第１アンテナ４から無線回路７までの特性インピーダンスは、第１アンテナ４の特性インピーダンスである５０Ω付近であることが望ましい。具体的には、第１信号線６及び第１端子５及び第２端子８および第２信号線９の合計の特性インピーダンスは、５０Ω±１０Ωであることが望ましい。これにより、高周波信号の伝送路における不整合損失を防ぐことができる。   The second signal line 9 is constituted by, for example, a coaxial cable, a microstrip line, or a strip line. Note that the characteristic impedance from the first antenna 4 to the wireless circuit 7 is desirably around 50Ω, which is the characteristic impedance of the first antenna 4. Specifically, the total characteristic impedance of the first signal line 6, the first terminal 5, the second terminal 8, and the second signal line 9 is desirably 50Ω ± 10Ω. Thereby, mismatch loss in the transmission path of the high frequency signal can be prevented.

また、無線通信装置２が無線通信装置用アダプタ１に挿入接続された場合、上方向から見て、図２に示す無線通信装置用アダプタ１の第１信号線６と図３に示す無線通信装置２の第２信号線９とは重ならないことが望ましい。この構成により、第１信号線６と第２信号線９との距離が大きくなるので、第１信号線６を通る高周波信号と第２信号線９を通る高周波信号とが干渉しあうことを抑制することができる。従って、第１アンテナ４で受信した高周波信号を、第１アンテナ４から無線回路７まで効率よく伝送させることができる。   When the wireless communication device 2 is inserted and connected to the wireless communication device adapter 1, the first signal line 6 of the wireless communication device adapter 1 shown in FIG. 2 and the wireless communication device shown in FIG. It is desirable that the second signal line 9 does not overlap the second signal line 9. With this configuration, since the distance between the first signal line 6 and the second signal line 9 is increased, the high-frequency signal passing through the first signal line 6 and the high-frequency signal passing through the second signal line 9 are prevented from interfering with each other. can do. Therefore, the high frequency signal received by the first antenna 4 can be efficiently transmitted from the first antenna 4 to the radio circuit 7.

なお、第１端子５は、Ａ−１１の端子以外の無線通信装置用アダプタ１における他の端子であっても構わない。   The first terminal 5 may be another terminal in the wireless communication device adapter 1 other than the terminal A-11.

また、第２端子８は、Ｐｃ−１１の端子以外の無線通信装置２における他の端子であっても構わない。   The second terminal 8 may be another terminal in the wireless communication device 2 other than the terminal of Pc-11.

なお、無線通信装置２は、記憶部を有していても構わない。   Note that the wireless communication device 2 may include a storage unit.

図４に示すように、無線通信装置２は、さらに、第２アンテナ１２と、アンテナ切替スイッチ１３とを有する。さらにまた、アンテナ切替スイッチ１３と第２端子８、アンテナ切替スイッチ１３と無線回路７、アンテナ切替スイッチ１３と処理回路１１、及びアンテナ切替スイッチ１３と第２アンテナ１２は各々第２信号線９によって電気的に接続されている。   As shown in FIG. 4, the wireless communication device 2 further includes a second antenna 12 and an antenna changeover switch 13. Furthermore, the antenna selector switch 13 and the second terminal 8, the antenna selector switch 13 and the radio circuit 7, the antenna selector switch 13 and the processing circuit 11, and the antenna selector switch 13 and the second antenna 12 are electrically connected by the second signal line 9. Connected.

処理回路１１は、アンテナ切替スイッチ１３を使って、無線通信装置用アダプタ１の第１アンテナ４と無線通信装置２の第２アンテナ１２のうち、受信電界強度の高い方を選択的に切替える。これにより、無線回路７は、第１アンテナ４からの信号と第２アンテナ１２からの信号とをダイバーシティ方式で受信することができる。なお、ダイバーシティ方式は、時間ダイバーシティ方式、空間ダイバーシティ方式、偏波ダイバーシティ方式、周波数ダイバーシティ方式などである。この構成により、無線通信装置２における受信特性を向上させることができる。   The processing circuit 11 uses the antenna selector switch 13 to selectively switch one of the first antenna 4 of the wireless communication device adapter 1 and the second antenna 12 of the wireless communication device 2 that has a higher received electric field strength. Thereby, the radio circuit 7 can receive the signal from the first antenna 4 and the signal from the second antenna 12 by the diversity method. The diversity method includes a time diversity method, a space diversity method, a polarization diversity method, a frequency diversity method, and the like. With this configuration, reception characteristics in the wireless communication device 2 can be improved.

また、図５に示すように、情報処理端末３が、第３アンテナ１４と、この第３アンテナ１４と無線通信装置用アダプタ１を電気的に接続する第３信号線１５とを有し、無線回路７が、無線通信装置用アダプタ１の第１アンテナ４と情報処理端末３の第３アンテナ１４とを、ダイバーシティ方式で受信しても構わない。この構成により、無線通信装置２における受信特性を向上させることができる。   As shown in FIG. 5, the information processing terminal 3 includes a third antenna 14 and a third signal line 15 that electrically connects the third antenna 14 and the wireless communication device adapter 1.
