Therefore, since the antenna element 61 is connected to the second circuit unit 41, the antenna element 61 functions as a radiating element of the antenna.
- the second suppression unit 43 passes a signal in the second frequency f2 band. That is, in the second frequency f2 band, the antenna element 61 and the second circuit unit 41 are connected at a high frequency. Then, the second circuit unit 41 connected to the antenna element 61 performs a predetermined process on the signal in the second frequency f2 band resonated by the antenna element 61. Thus, an antenna is constituted by the antenna element 61.

Thereby, the antenna sensitivity of the mobile phone 1 can be improved.
- the mobile phone 1 has a configuration in which the first circuit unit 32 and the antenna element 61 are arranged in the operation unit side body 2. Therefore, the balance between the length that functions as the radiating element of the antenna and the length that functions as the ground portion of the antenna can be improved. Thereby, the antenna sensitivity of the mobile phone 1 can be improved.

Accordingly, it is possible to improve the antenna sensitivity of an antenna (for example, a dipole antenna) configured by the entire operation unit side body 2, the display unit side body 3, and the connection unit 4.
- the mobile phone 1 includes a first suppression unit 42 and a second suppression unit 43.

Description
このため、第1筐体の第1導電部の長さと第2筐体の第2導電部との長さが略同一である携帯電話機においては、例えば、第1筐体の第1導電部の長さと、第2筐体の第2導電部の長さと連結部の第3導電部の長さとの和により得られる長さとには、長さの差が生じる。この場合、グランドの電気的な長さとアンテナの電気的な長さのバランスが不均等となる。そのため、アンテナ感度の低下が生じてしまうという問題があった。
図1により、第1実施形態に係る携帯端末としての携帯電話機1における基本構造を説明する。図1は、携帯電話機1を開いた状態を示す外観斜視図である。
即ち、携帯電話機1は、連結部4を介して連結された操作部側筐体2と表示部側筐体3とを相対的に回転(回動)することにより、操作部側筐体2と表示部側筐体3とを互いに開いた状態である開状態にしたり、操作部側筐体2と表示部側筐体3とを折り畳んだ状態である閉状態にしたりできる。
なお、図2においては、操作部側筐体2の内部の構成部材については、第1導電部31、第1回路部32、第2回路部41、第1電子部品としてのアンテナ素子61等のみを示している。また、表示部側筐体3の内部の構成部材については、第2導電部33のみを示している。また、連結部4の内部構成部材については、第3導電部34のみを示している。但し、図2は、操作部側筐体2、表示部側筐体3及び連結部4のそれぞれの内部構造を限定するものではない。
また、図2においては、仮想的に、第1導電部31、第2導電部33、第3導電部34、アンテナ素子61、第1回路部32、第2回路部41等のうちのいずれか同士を接続線で接続することにより接続状態を示している。本実施形態においては、図2に示す接続線は、各部の接続状態を説明するためのものであり、後述する信号の経路長には説明の便宜上含まないものとする。
第1回路部32は、グランド部35と、給電部36と、グランド部35及び給電部36に接続される信号処理部37とを備える。
f1=1/2π√(L1C1)・・・(1)
Z1=jωL1+1/(jωC1)・・・(2)
ここで、ω=2πf1である。
f2=1/2π√(L2C2)・・・(3)
また、インピーダンスZ2は、(4)式によって求められる。
Z2=jωL2+1/(jωC2)・・・(4)
ここで、ω=2πf2である。
また、第3導電部34は、連結部4の内部に配置された導電部により構成される。第3導電部34は、表示部側筐体3の長さ方向Aに長く形成される。第3導電部34は、連結部4における表示部側筐体3の長さ方向Aに直交する方向Bの一方の端部側に、表示部側筐体3の長さ方向Aに沿って配置される。第3導電部34における表示部側筐体3側の端部は、第2導電部33の長さ方向Aの端部に接続される。第3導電部34における操作部側筐体2側の端部は、第1回路部32の給電部36に接続される。これにより、第3導電部34は、第2導電部33に高周波的に接続されると共に、第1回路部32の給電部36に高周波的に接続される。
図2に示すように、第1導電部31における操作部側筐体2の長さ方向Aにおける長さX1a(第1の周波数f1帯域の信号の経路長)は、第1導電部31における操作部側筐体2の長さ方向Aに沿う経路長であって、第1導電部31における連結部4側の端部から連結部4とは反対側の端部までの第1の周波数f1帯域の信号の経路長ある。また、アンテナ素子61における長さ方向(操作部側筐体2の幅方向B)における長さX1b(第1の周波数f1帯域の信号の経路長)は、アンテナ素子61における長さ方向(操作部側筐体2の幅方向B)に沿う経路長であって、アンテナ素子61における一方の端部から他方の端部までの第1の周波数f1帯域の信号の経路長である。
つまり、第1長さX1(X1a+X1b)は、第1導電部31におけるグランド部35との接点からアンテナ素子61までの第1の周波数f1帯域の信号の経路長である。
第2導電部33における表示部側筐体3の長さ方向Aにおける長さX2a(第1の周波数f1帯域の信号の経路長)は、第2導電部33における表示部側筐体3の長さ方向Aに沿う経路長であって、第2導電部33における連結部4側の端部から連結部4とは反対側の端部までの第1の周波数f1帯域の信号の経路長ある。また、第3導電部34の表示部側筐体3の長さ方向Aにおける長さX2b(第1の周波数f1帯域の信号の経路長)は、第3導電部34における表示部側筐体3の長さ方向Aに沿う経路長であって、第3導電部34における表示部側筐体3側の端部から操作部側筐体2側の端部までの第1の周波数f1帯域の信号の経路長である。
つまり、第2長さX2(X2a+X2b)は、第3導電部34における給電部36との接点から第2導電部33までの第1の周波数f1帯域の信号の経路長である。
まず、図2から図5により、第1の周波数f1帯域の信号が携帯電話機1に入力された場合について説明する。
図2から図5に示すように、第1の周波数f1帯域の信号が携帯電話機1に入力された場合、第1抑制部42は、第1の周波数f1帯域の信号を通過させる。つまり、第1導電部31とアンテナ素子61とは、高周波的に接続される。従って、第1導電部31がグランド部35に電気的に接続されているため、第1導電部31及びアンテナ素子61は、アンテナのグランド部として機能する。また、第2導電部33及び第3導電部34は、アンテナの放射素子として機能する。一方、第2抑制部43は、第2の周波数f2とは異なる周波数帯域の信号の通過を低減する。そのため、第2抑制部43は、第1の周波数f1帯域の信号の通過を低減する。つまり、アンテナ素子61と第2回路部41とは、第1の周波数f1帯域においては、高周波的に接続されにくくなる。
そして、第1回路部32の信号処理部37は、給電部36から供給された第1の周波数f1帯域の信号に対して所定の処理を行う。
このように、表示部側筐体3及び操作部側筐体2の全体は、1個のアンテナ(例えば、ダイポールアンテナ)を構成する。
図2から図5に示すように、第2の周波数f2帯域の信号が携帯電話機1に入力された場合、第1抑制部42は、第1の周波数f1とは異なる周波数帯域の信号の通過を低減する。そのため、第1抑制部42は、第2の周波数f2帯域の信号の通過を低減する。つまり、第2の周波数f2帯域においては、アンテナ素子61と第1抑制部42に接続されたグランドとは、高周波的に接続されにくくなる。従って、アンテナ素子61が第2回路部41に接続されているため、アンテナ素子61は、アンテナの放射素子として機能する。一方、第2抑制部43は、第2の周波数f2帯域の信号を通過させる。つまり、第2の周波数f2帯域においては、アンテナ素子61と第2回路部41とは、高周波的に接続される。
そして、アンテナ素子61に接続された第2回路部41は、アンテナ素子61により共振される第2の周波数f2帯域の信号に対して所定の処理を行う。
このように、アンテナ素子61によりアンテナが構成される。
携帯電話機1は、操作部側筐体2の第1導電部31とアンテナ素子61とが第1回路部32のグランド部35に接続され、表示部側筐体3の第2導電部33及び連結部4の第3導電部34が給電部36に高周波的に接続される。そのため、操作部側筐体2、表示部側筐体3及び連結部4の全体は、アンテナ(例えば、ダイポールアンテナ)を構成する。これにより、携帯電話機1のアンテナ感度を向上させることができる。
また、図6においては、仮想的に、第1導電部31、第2導電部33、第3導電部34、アンテナ素子61、レシーバ22、第1回路部32、第2回路部41等のうちのいずれか同士を接続線で接続することにより接続状態を示している。本実施形態においては、図6に示す接続線は、各部の接続状態を説明するためのものであり、後述する信号の経路長には説明の便宜上含まないものとする。
また、レシーバ22は、レシーバ22の長さ方向(表示部側筐体3の幅方向B)における一方の端部が第2導電部33に高周波的に接続される。
ここで、図6及び図7により、制御部55による第1選択部51及び第2選択部52の制御について説明する。
図7に示すように、制御部55は、第1選択部51及び第2選択部52のいずれも遮断する状態を選択する第1状態と、第1選択部51及び第2選択部52のいずれも接続する状態を選択する第2状態と、に切り替えることができる。
この場合、第1導電部31における操作部側筐体2の長さ方向Aにおける第3長さX3(第1の周波数f1帯域の信号の経路長)は、第2導電部33における表示部側筐体3の長さ方向Aにおける長さX4a(第1の周波数f1帯域の信号の経路長)と第3導電部34における表示部側筐体3の長さ方向Aにおける長さX4b(第1の周波数f1帯域の信号の経路長)との和により得られる第4長さX4(X4a+X4b)と略等しく(X3=X4)なっている。そのため、アンテナの放射素子として機能する第2導電部33の長さX4a及び第3導電部34の長さX4bの和により得られる第4長さX4と、アンテナのグランド部として機能する第1導電部31の第3長さX3と、は、略等しい。
図6に示すように、第1導電部31における操作部側筐体2の長さ方向Aにおける第3長さX3(第1の周波数f1帯域の信号の経路長)は、第1導電部31における操作部側筐体2の長さ方向Aに沿う経路長であって、第1導電部31における連結部4側の端部から連結部4とは反対側の端部までの第1の周波数f1帯域の信号の経路長ある。
つまり、第3長さX3は、第1導電部31におけるグランド部35との接点から第1導電部31におけるアンテナ素子61との接点までの第1の周波数f1帯域の信号の経路長である。
第2導電部33における表示部側筐体3の長さ方向Aにおける長さX4a(第1の周波数f1帯域の信号の経路長)は、第2導電部33における表示部側筐体3の長さ方向Aに沿う経路長であって、第2導電部33における連結部4側の端部から連結部4とは反対側の端部までの第1の周波数f1帯域の信号の経路長ある。また、第3導電部34における表示部側筐体3の長さ方向Aにおける長さX4b(第1の周波数f1帯域の信号の経路長)は、第3導電部34における表示部側筐体3の長さ方向Aに沿う経路長であって、第3導電部34における表示部側筐体3側の端部から操作部側筐体2側の端部までの第1の周波数f1帯域の信号の経路長である。
つまり、第4長さX4(X4a+X4b)は、第3導電部34における給電部36との接点から第2導電部33までの第1の周波数f1帯域の信号の経路長である。
この場合、第3長さX3(X5a(第1の周波数f1帯域の信号の経路長))とアンテナ素子61の長さ方向(操作部側筐体2の幅方向B)における長さX5b(第1の周波数f1帯域の信号の経路長)の和により得られる第5長さX5(X3+X5b)は、第4長さX4(X6a(第1の周波数f1帯域の信号の経路長))とレシーバ22の長さ方向(表示部側筐体3の幅方向B)における長さX6b(第1の周波数f1帯域の信号の経路長)の和により得られる第6長さX6と略等しく(X5=X6)なるように接続される。そのため、アンテナの放射素子として機能する第4長さX4とレシーバ22の長さX6bの和により得られる第6長さX6(X4+X6b)と、アンテナのグランド部として機能する第3長さX3とアンテナ素子61の長さX5bの和により得られる第5長さX5と、は、略等しい。
第3長さX3は、前述の通り、グランド部35から第1導電部31までの第1の周波数f1帯域の信号の経路長である。また、アンテナ素子61の長さ方向(操作部側筐体2の幅方向B)における長さX5b(第1の周波数f1帯域の信号の経路長)は、アンテナ素子61における長さ方向(操作部側筐体2の幅方向B)に沿う経路長であって、アンテナ素子61における一方の端部から他方の端部までの第1の周波数f1帯域の信号の経路長である。
つまり、第5長さX5(X3+X5b)は、第1導電部31におけるグランド部35との接点からアンテナ素子61までの第1の周波数f1帯域の信号の経路長である。
第4長さX4は、前述の通り、給電部36から第3導電部34を介して第2導電部33までの第1の周波数f1帯域の信号の経路長である。また、レシーバ22の長さ方向(表示部側筐体3の幅方向B)における長さX6b(第1の周波数f1帯域の信号の経路長)は、レシーバ22における長さ方向(表示部側筐体3の幅方向B)に沿う経路長であって、レシーバ22における一方の端部から他方の端部までの第1の周波数f1帯域の信号の経路長である。
つまり、第6長さX6(X4+X6b)は、第3導電部34における給電部36との接点からレシーバ22までの第1の周波数f1帯域の信号の経路長である。
制御部55により第1選択部51及び第2選択部52が制御される。制御部55は、第1導電部31における操作部側筐体2の長さ方向Aにおける第3長さX3は、第2導電部33における表示部側筐体3の長さ方向Aにおける長さX4aと第3導電部34における表示部側筐体3の長さ方向Aにおける長さX4bとの和により得られる第4長さX4と略等しく(X3=X4)なるように接続される状態と、第3長さX3(X5a)とアンテナ素子61の長さ方向(操作部側筐体2の幅方向B)における長さX5bの和により得られる第5長さX5は、第4長さX4(X6a)とレシーバ22の長さ方向(表示部側筐体3の幅方向B)における長さX6bの和により得られる第6長さX6と略等しく(X5=X6)なるように接続される状態と、に切り替えることができるように構成される。
例えば、本実施形態では、第1導電部31が第1回路部32のグランド部35に接続され、第3導電部34が第1回路部32の給電部36に接続される構成としているが、第1導電部31が第1回路部32の給電部36に接続され、第3導電部34が第1回路部32のグランド部35に接続される構成であってもよい。
