Description

具有多副天线的多频带无线电话
                           发明背景
技术领域
本发明涉及无线电话，尤其涉及多带无线电话的天线结构。
背景技术
无线电话长期来需在多个频带中工作。旧的蜂窝网电话操作在800MHz，而较先进的PCS(个人通信系统)电话工作在1900MHz。这可以由单一天线处理，在第一个频带中作为四分之一波长天线工作，而在第二个中作为半波长天线。然而，可提供附加的特性时，必须使用附加的天线。这是不合需要的，因为它增加了希望轻便、紧凑且(最重要的)便携的产品——无线电话的重量和体积。
                           发明概述
本申请克服了原有技术的限制，至少附加的特性是GPS和蓝牙这个情况下。
GPS是全球定位系统。基于地面的接收机从几个卫星准确接收定时信号。每个卫星有准确可知的位置，这个位置的编码也被包括在信号中。通过记录接收每个信号时间(以及时间上的差别)，接收机能计算它自己的位置。GPS工作在1575MHz。
蓝牙是蓝牙专用业务组的方案，它的网站自提出申请之日起(在http：//www.bluetooth.com)就是无线的。它这样做是通过使用低功率、小范围(10-100米)工作在2400-2483MHz的无线电链路。
本发明在有单一外部天线的单个设备中提供无线电话、GPS和蓝牙性能。示出了三个实施例。
在第一个实施例中，电话被设计为只在一个电话频带中工作。响应于接入电话和GPS，外部天线对多频带进行调谐。天线共用器或电子开关分离电话和GPS信号。内部天线用于蓝牙。
在第二个实施例中，电话被设计为在两个电话频带中工作。内部天线用于两个电话频带。单个外部天线用于GPS和蓝牙，带有同类的天线共用器和电子开关。
第三个实施例类似于第二个，但是使用了两副内部天线，一副用于GPS而另一副用于蓝牙。省去了天线共用器和电子开关。
根据本发明，提供一种无线电话，包括：电话收发机；与所述电话收发机相连接的外部天线；与所述外部天线相连接的GPS接收机；信号分离器，所述信号分离器连接成用于：从所述外部天线接收电话信号和GPS信号；分离所述电话信号和所述GPS信号；把所述电话信号加到所述电话收发机；以及把所述GPS信号加到所述GPS接收机；蓝牙收发机；以及与所述蓝牙收发机相连接的内部天线。
根据本发明，还提供一种无线电话，包括：电话收发机；与所述电话收发机相连接的外部天线；GPS接收机；与所述GPS接收机相连接的内部天线；与所述内部天线相连接的蓝牙收发机；以及信号分离器，所述信号分离器连接成用于：从所述内部天线接收蓝牙信号和GPS信号；分离所述蓝牙信号和所述GPS信号；把所述蓝牙信号加到所述蓝牙收发机；以及把所述GPS信号加到所述GPS接收机。
根据本发明，还提供一种无线电话，包括：电话收发机；与所述电话收发机相连接的外部天线；GPS接收机；与所述GPS接收机相连接的GPS内部天线；蓝牙收发机；与所述蓝牙收发机相连接的蓝牙内部天线，其中，所述GPS内部天线与蓝牙内部天线是分离的。
                        附图简述
图1是本发明第一个实施例的框图。
图2是本发明第二个实施例的框图。
图3是本发明第三个实施例的框图。
                      较佳实施例详述
图1是本发明第一个实施例的框图。无线电话(102)有电话收发机(104)、GPS接收机(106)和蓝牙接收机(108)。外部天线从远距离电话基站(112)接收电话信号，并也从远距离GPS卫星群接收GPS信号。这些信号信号分离器分离电话信号和GPS信号，并把电话信号加到电话收发机(104)把GPS信号加到GPS接收机(106)。远距离蓝牙设备把信号发送到蓝牙天线(120)，它把蓝牙信号应用于蓝牙接收机(108)。
图2是本发明第二个实施例的框图。图2一般与图1相同，但有两处例外。
第一，图1的外部天线(110)成为了外部天线(210)，其原因在于天线(210)已优化成在两个频带上接收电话信号而不是在一个频带上。从第一远距离基站(222)接收在第一频带上的信号，而从第二远距离基站(224)接收在第二频带上的信号。两个基站可以合设并甚至可以共用一副天线，但由于它们工作在不同频带上，认为彼此分开设置。图1的单频带电话收发机(104)被改变成图2的双频带电话收发机(204)。在本技术中已知共用普通天线的双频带电话收发机。
第二.图1的信号分离器(116)成为了图2的信号分离器(216)，其原因在于分离器(216)分离GPS和蓝牙信号而不是GPS和电话信号。图1的内部天线(120)成为了图2的内部天线(220)，其原因在于后者已优化成接收GPS和蓝牙信号，而不是只接收蓝牙信号。信号分离器(216)从内部GPS天线(220)接收蓝牙信号和GPS信号并分离两个信号。然后它把蓝牙信号加到蓝牙收发机(108)，把GPS信号加到GPS接收机(106)。
图3是本发明第三个实施例的框图。图3一般与图2相同，但有一处例外。已去除了信号分离器(216)，而添加了分离的内部GPS天线(326)，它直接把信号加到GPS接收机。如图1那样，蓝牙天线(120)把蓝牙信号加到蓝牙收发机(108)。
工业应用
本发明能用于工业开发并能在想要提供带有GPS和的无线电话的任何时候实现及使用本发明。在这里显示的方法互相分离，可能是完全传统的，但它们的组合属于本发明的权利要求。
尽管描述了设备和方法的各种模式，本发明真实的精神和范围不限于此，但它只限于以下按本发明提出的权利要求及其等同体。
