11 操作キー群
20 第1のアンテナ部
100 放送波受信部(第1の信号処理手段)
101 放送波処理部
103 回路切替部
103a 第1の整合回路
103b 第2の整合回路
103c 第1の切替スイッチ
103d 第2の切替スイッチ
150 通信部(第2の信号処理手段)

200 処理部
205 受信抑制部
また、上述した携帯電話機1では、チューナブル・アンテナとしての第1のアンテナ部20により通信を行っているときに(例えば、テレビを視聴しているときに)、第2のアンテナ部151を用いてCDMA通信を行う場合(メールの送受信等を行う場合)、第1のアンテナ部20に接続されている調整回路を適宜切り替えることにより、第2のアンテナ部151によるCDMA通信方式の低周波数帯の信号の干渉の低減を図り、好適に第1のアンテナ部20による通信を行い、かつ第2のアンテナ部151による通信を行うことができる機能を有している。
また、上述した携帯電話機1では、ユーザの接触に起因する通信感度の劣化(誘電損失)を低減するために、一定条件下において、第1のアンテナ部20の共振周波数fcを高周波側にシフトする機能を有している。ここで、当該機能は、操作キー群11と、受信抑制部205と、アンテナ制御回路102とが協調して動作することによって実現される。
Claims (2)
- 第1のアンテナにより送信される送信信号又は受信される受信信号に対して所定の信号処理を行う第1の信号処理手段と、
第2のアンテナにより送信される送信信号又は受信される受信信号に対して所定の信号処理を行う第2の信号処理手段と、
前記第2のアンテナにより送信される前記送信信号又は受信される前記受信信号の強度に基づいて、前記第1のアンテナの共振周波数の帯域幅を狭め、当該帯域幅を狭めることにより、前記第2のアンテナにより送信される前記送信信号又は受信される前記受信信号が前記第1のアンテナにより受信されるのを抑制する受信抑制手段と、を有することを特徴とする携帯通信機器。 - 第1のアンテナにより送信される送信信号又は受信される受信信号に対して所定の信号処理を行う第1の信号処理手段と、第2のアンテナにより送信される送信信号又は受信される受信信号に対して所定の信号処理を行う第2の信号処理手段と、を備える携帯通信機器における受信抑制方法であって、
前記第2のアンテナにより送信される前記送信信号又は受信される前記受信信号の強度に基づいて、前記第1のアンテナの共振周波数の帯域幅を狭め、当該帯域幅を狭めることにより、前記第2のアンテナにより送信される前記送信信号又は受信される前記受信信号が前記第1のアンテナにより受信されるのを抑制する抑制工程を有することを特徴とする受信抑制方法。
