Description

连接AGPS模块和无线接入终端主板的部件及终端 技术领域
本实用新型涉及滤波技术，尤其涉及一种连接AGPS模块和无线接入终端主板的部件、及具有AGPS模块的无线接入终端。
背景技术
本申请发明人在实现本申请实施例技术方案的过程中，至少发现相关技术中存在如下技术问题：
长期演进(LTE)的出现促进了无线宽带接入技术和产业的发展，随着业务的需求越来越广泛，要求LTE产品提供的功能也越来越大。对于手机和无线接入产品等，目前美国以及欧洲产品基本都必需带有辅助全球卫星定位系统(AGPS，Assisted Global Positioning System)的定位功能，例如，采用如图1所示天线布局示意图中的AGPS模块12来实现定位功能，AGPS是一种GPS的运行方式。它可以利用手机基站的资讯，配合传统GPS卫星，让定位的速度更快。
AGPS解决方案的优势主要在其定位精度上，在室外等空旷地区，其精度在正常的GPS工作环境下，可达10米左右，堪称目前定位精度最高的一种定位技术。该技术的另一优点为：首次捕获GPS信号的时间一般仅需几秒，不像GPS的首次捕获时间可能要2～3分钟。
然而，现有技术存在的问题是：由于AGPS接收灵敏度通常是-140dB左右，信号非常弱，非常容易受到干扰，导致定位偏差较大，尤其是在多天线产品中，常常受到产品自身产生的干扰，对于这个问题，相关技术中并未存在有效的解决方案。
发明内容
有鉴于此，本实用新型实施例希望提供一种无线接入终端的天线滤波装置及无线接入终端，能通过对杂波信号进行过滤来减少AGPS干扰，从而提高了AGPS的灵敏度，以确保AGPS的定位精度。
本实用新型实施例的技术方案是这样实现的：
本实用新型的一种连接AGPS模块和无线接入终端主板的部件，所述部件包括：导电部件；
所述导电部件位于所述AGPS模块与所述主板之间，所述导电部件填充满所述AGPS模块与所述主板之间的缝隙。
上述方案中，所述导电部件为导电泡棉，在所述导电泡棉的本体上具有外围的腔体和腔体中用于滤波的内嵌结构体；
所述内嵌结构体的形状至少包括：三角形。
上述方案中，所述导电泡棉的厚度大于AGPS模块与所述主板之间的所述缝隙的缝隙厚度。
上述方案中，所述导电泡棉的横向长度与所述AGPS模块的长度一致。
上述方案中，所述腔体和所述内嵌结构体为装配式组合成型；或者，
所述腔体和所述内嵌结构体为一体成型。
上述方案中，所述导电泡棉的形状与所述AGPS模块的形状相对应，包括规则形状或非规则形状；
所述规则形状至少包括：四边形、梯形或菱形。
上述方案中，所述内嵌结构体的形状为三角形时，所述内嵌结构体为内嵌三角形；
所述内嵌三角形包括：位于所述腔体内的横向三角形和/或纵向三角形。
本实用新型的一种具有AGPS模块的无线接入终端，所述无线接入终端包括：AGPS模块、无线接入终端的主板、导电部件；
所述AGPS模块以插接的方式与所述主板相连接；
所述导电部件位于所述AGPS模块与所述主板之间，所述AGPS模块与所述主板之间的缝隙由所述导电部件填充。
上述方案中，所述导电部件为如上述方案中任一项所述的部件。
本实用新型的连接AGPS模块和无线接入终端主板的部件，所述部件包括：导电部件；所述导电部件位于所述AGPS模块与所述主板之间，所述导电部件填充满所述AGPS模块与所述主板之间的缝隙。由于AGPS模块与所述主板之间的缝隙由所述导电部件填充，通过导电部件会填满所述缝隙，则AGPS模块与主板间不能再耦合辐射出杂波信号，从而实现了对杂波信号进行过滤，以减少AGPS干扰，从而提高了AGPS的灵敏度，以确保AGPS的定位精度。

本实用新型实施例的适用产品领域为无线路由等无线接入终端，本实用新型实施例作为一种新型的减少AGPS干扰的无线方案，为一种减少AGPS灵敏度干扰的实用方案，可以有效解决多功能，比如多天线产品中AGPS接收灵敏度易受干扰以及天线低频段性能较差的问题，尤其适用于目前WCDMA和LTE无线路由产品。

这里需要指出的是，本实用新型实施例的所述导电部件为上述方案中任一项所述的部件。
综上所述，采用本实用新型实施例提供的以上方案，可以有效的消除AGPS模块与主板之间的缝隙处耦合出的杂波信号干扰，并消弱了来自AGPS模块和主板自身所辐射出的杂波信号，能提高AGPS天线的接收灵敏度，解决了LTE等路由产品的AGPS灵敏度干扰问题。
以下用具体的一个应用场景进行举例，结合附图对本实用新型实施例进行说明。
如图1所示，本产品为一款无线接入终端，包括：AGPS模块12与主板13，AGPS模块12与主板13采用插接式连接，AGPS模块12带有AGPS定位功能，同时要求满足LTE band 2/4/5/12/17、CDMA800/1900以及WIFI2.4G/5.8G业务。LTE支持MIMO技术，需要两个天线，所述无线接入终端还包括：LTE主天线4和LTE辅天线5；WIFI支持双路工作，需要4个天线，所述无线接入终端还包括：5.8G WIFi天线1、5.8G WIFi天线2、2.4G WIFi天线1、2.4G WIFi天线2，如图1中的标号6、7、8、9所示。
所述无线接入终端还包括：CDMA天线10和GPS天线11，则本产品共有8个天线，受到主板尺寸的限制，AGPS天线与其它天线的隔离度不能通过拉远天线之间的位置来提高。因为非常容易受到其他7个天线的干扰。整个产品的天线布局如图1所示，目前已经是最佳布局方案，GPS天线11已经远离LTE主天线4，但是在产品的实际测试中，AGPS接收灵敏度只有-135.2dB,而且出现了12颗假星，不能满足产品的设计要求。
AGPS灵敏度偏低的原因来自于两个方面，第一，AGPS模块12自身以及主板13自身辐射出来的杂波信号；第二，AGPS模块以及主板之间的缝隙处会耦合出杂波信号。
应用上述本实用新型实施例的方案来改善如下：
如图2所示，设计一块特殊形状的导电泡棉，导电泡棉本体1包括：导电泡棉的腔体110，导电泡棉腔体中内嵌的纵向三角形120，导电泡棉腔体中内嵌的横向三角形130。
AGPS工作频点1.57Ghz(自身频段)，导电泡棉的宽度采用1/4波长，约19mm；导电泡棉的横向长度与AGPS模块长度一致，这里取30mm。
对于导电泡棉的厚度不作特殊要求，可以用0.8mm。在导电泡棉上设计内嵌三角形(尖峰三角形)来吸波，可以在横向和纵向上都设计尖峰三角形，横向三角形130的底宽度4mm，高3mm；纵向三角形120的底宽度3mm，高度是6mm。
如图3所示为夹心层结构，此时，导电泡棉1位于AGPS模块12与主板13之间，以便将AGPS模块12与主板13之间的缝隙由导电泡棉1填满，可以起到滤波效果。
如图4所示，装配使用时，可以将导电泡棉贴在AGPS模块12下方的位置。此时AGPS模块12与主板13之间的缝隙由于有了导电泡棉，缝隙被填满，不能再耦合辐射出杂波，同时主板13和AGPS模块12自身辐射出的杂波在导电泡棉包括内嵌三角形的腔体内进行多次反射，不断衰减，也能起到滤波效果或称吸波效果。此时测试可以获得的数据为：AGPS的灵敏度测试值-147.1dB，比之前提升了10dB以上，且此时已经没有一颗假星，说明干扰已经大大降低了。
在本具体应用场景中采用本实用新型的方案，通过改变导电泡棉的外形尺寸以及内嵌三角型的尺寸，能消除除去AGPS工作频段之外其他频段的杂波信号，能提高AGPS天线的接收灵敏度，解决了LTE等路由产品的AGPS灵敏度干扰问题。可以大量推广到其他无线终端产品中，并不限于本具体应用场景所描述的无线接入终端。
以上所述，仅为本实用新型的较佳实施例而已，并非用于限定本实用新型的保护范围。
