Description

无线通信装置
技术领域
本发明涉及一种无线通信装置，尤其涉及一种可提高通话性能的无线通信装置。
背景技术
用户在使用现有的无线通信装置进行通话时，头部及手部比较靠近无线通信装置，容易对其内所设置天线产生干扰，使天线的谐振频率往高频偏移，影响天线收发信号的稳定性，造成无线通信装置通话性能不佳。
发明内容
针对上述问题，有必要提供一种可提高通话性能的无线通信装置。
一种无线通信装置，该无线通信装置包括传感器、中央处理器（central processing unit，CPU）、天线模块及匹配电路；该传感器与该CPU电性连接，该天线模块经该匹配电路与该CPU相连；该传感器感测该无线通信装置处于通话状态并有外部物体进入该传感器的设定距离时发送感测信号至该CPU，该CPU接收该感应信号并发送控制信号至匹配电路，该匹配电路控制该天线模块的谐振频率往低频偏移。
本发明所述的无线通信装处于通话状态时控制天线模块的谐振频率往低频偏移，抵消甚至消除天线模块因用户头部或手部的干扰而引起的谐振频率往高频偏移，从而获得较佳的通话性能。
附图说明
图1是本发明的无线通信装置的部分电路图。
主要元件符号说明
无线通信装置 100

CPU 20
天线模块 30
匹配电路 40
变容二极管 D

电阻 R
第二电容 C2
如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
请参阅图1，本发明较佳实施例的无线通信装置100包括传感器10、中央处理器（central processing unit，CPU）20、天线模块30及匹配电路40。该传感器10与该CPU20电性连接，该天线模块30经该匹配电路40与该CPU20相连。
该传感器10设置于无线通信装置100内，较佳的设置于无线通信装置100的听筒附近，用以在无线通信装置100正处于通话状态时感测是否有外部物体进入传感器的设定距离，如用户的手部或头部是否靠近或接触该无线通信装置100，并在外部物体靠近或接触该无线通信装置100时发送感测信号至CPU20。在本较佳实施例中，该传感器10为光传感器，其可根据外部物体靠近或接触该无线通信装置100时该传感器10接收的光线的变化，判断外部物体是否靠近或接触该无线通信装置100。可以理解，该传感器10也可以为接近传感器（proximity sensor），当外部物体进入接近传感器的设定距离内时，该接近传感器可以检测到。
该CPU20接收传感器10发送的感测信号，并发送控制信号至匹配电路40，控制匹配电路40对天线模块30的谐振频率进行调节。通常，该CPU20还会关闭无线通信装置100的屏幕以省电。
该天线模块30用以收发无线通信信号，其包括单极子天线。
该匹配电路40包括变容二极管D、第一电容C1、电阻R及第二电容C2。
该变容二极管D的阴极经第一电容C1与天线模块30电性连接，阳极接地。该电阻R与第二电容C2串联后一端电连接至第一电容C1与天线模块30之间，另一端接地。该CPU20电连接至变容二极管D与第一电容C1之间。当CPU20发送控制信号至变容二极管D时，变容二极管D的等效电容改变，从而使得天线模块30的谐振频率往低频偏移，进而抵消甚至消除因用户头部或手部的干扰而引起的天线模块30的谐振频率往高频的偏移，从而使得无线通信装置100具有较佳的通话效果。
用户在使用无线通信装置100进行通话时，传感器10感测到用户头部靠近或接触该无线通信装置100，并发送感测信号至CPU20，该CPU20接收到该感应信号后发送控制信号至匹配电路40以改变变容二极管D的电容，使得该匹配电路40控制天线模块30的谐振频率往低频偏移。
本发明所述的无线通信装置100处于通话状态时控制天线模块30的谐振频率往低频偏移，抵消甚至消除天线模块30因用户头部或手部的干扰而引起的谐振频率往高频偏移，从而获得较佳的通话性能。
