技术领域
本申请涉及天线技术领域，更具体地涉及应用于移动终端的天线装置及移动终端。
背景技术
随着无线通信技术的日益发展，天线设计已成为移动终端(如，手机)的瓶颈之一，原因在于：移动终端支持的无线技术种类繁多，除了需要支持移动蜂窝通信Cellular外，还需要支持WIFI、GPS、WiHD、NFC等无线技术，天线的数量随之大幅增加，因此，如何将各个天线加入到容积较小的移动终端中成为天线布局的一个难题；另一方面，人体(特别是头和手)对各个天线的性能有很大的影响，以手机为例，当用户手握手机时或者头部靠近手机时，对天线性能都会产生影响。主流的移动终端生产商均将头和手的状态影响状态下的天线性能列为移动终端的主要性能指标，因此，如何保证各种使用场景下各天线的性能成为天线布局的另一个难题。
在相关的现有技术中，天线均采用比较固定的布局形式，以手机为例，手机的主集天线位于手机下部，分集天线、WIFI/GPS天线位于手机上部(分别位于手机左上角和右上角)，并且，这样的天线布局几乎成为了业内的定式。
虽然这种布局方式可以保证各个天线在自由空间下的天线性能，但是，在各种使用场景下，例如，各种手握模式(包括横握和竖握)或接电话模式，天线性能仍然存在不同程度的恶化，影响用户的使用体验。

在本实施例中，由于所述第一至第四距离传感器(51-54)是用来探测手握或手握手机贴近脸部且对天线主体遮挡产生影响的情况，因此所述第一距离传感器51靠近所述第一宽频天线11设置，所述第二距离传感器52靠近所述第二宽频天线12设置，所述第三距离传感器53靠近所述第三宽频天线13设置，所述第四距离传感器54靠近所述第四宽频天线14设置，保证了当所述第一至第四宽频天线(11-14)被遮挡或未被遮挡，第一至第四距离传感器(51-54)也同步被遮挡或未被遮挡。
本实施例有物体或人到所述第一至第四宽频天线(11-14)的距离在预设的范围内的状态下，所述第一至第四距离传感器(51-54)获取的传感信号幅值大于或等于预设阈值，所述第一至第四距离传感器(51-54)向所述控制器3发送的是检测到所述第一至第四宽频天线(11-14)被遮挡的信号；无物体或人到所述第一至第四宽频天线(11-14)的距离在预设的范围内的状态下，所述第一至第四距离传感器(51-54)获取的传感信号幅值小于预设阈值，所述第一至第四距离传感器(51-54)向所述控制器3发送的是检测到所述第一至第四宽频天线(11-14)未被遮挡的信号。
所述控制器3还用于根据信号的强度控制开关阵列2选择信号强的宽频天线，使其与射频模块4导通。
在一个可选地实施例中，第一宽频天线11和第二宽频天线12为蜂窝通信天线，作为主天线收发信号，第三宽频天线13为蜂窝通信天线，作为分集天线收发信号，第四宽频天线3为WiFi天线，作为WiFi天线收发信号。
当距离传感器未检测到手的时候输出高电平，当距离传感器检测到手的时候输出低电平，距离传感器把检测结果汇报给控制器，控制器通过预设逻辑控制开关阵列以达到控制天线的目的。
以上所述仅为本申请的优选实施例，并不用于限制本申请，对于本领域技术人员而言，本申请可以有各种改动和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
