Description

一种车载防盗天线
技术领域
本发明涉及一种天线,具体是一种车载防盗天线。
背景技术
汽车防盗天线是汽车防盗系统天线。该天线与传统天线相比特点是:外观新颖,美观大方,结构小巧。可以很方便的吸附在玻璃上,方便快速。车载天线继续向着小巧隐形方向发展。其不足之处是:现有车载报警天线大多体积较大。放在驾驶室里不紧不美观大方,而且占用空间大。天线的频率一般为433兆,也偏高,在驾驶室里务必会对驾驶人员造成较大的辐射,影响驾驶人员的身体健康。
发明内容
本发明提供一种车载防盗天线,能减小天线的体积,降低发射频率,减小对人体健康的不良影响。
本发明是以如下技术方案实现的:一种车载防盗天线,其特征是:包括可以盖合在一起的上壳体和下壳体组成的壳体,在壳体中固定有放射导体,放射导体用信号线与壳体外的连接器插头连接;所述的信号线为同轴线缆,内层线为信号线连接在放射导体的微带线上,外层连接在放射导体的铜皮上做为接地导体。
使用方法是:将壳体的底部用胶片固定在车玻璃上。
由于采用了上述技术方案,本发明的有益效果是:体积小,安装固定方便,发射频率低,对人体危害小。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明外观结构示意图;
图2是图1的俯视图;
图3是本发明内部结构示意图。
图中:1、上壳体,2、下壳体,3、不干胶胶片,4、信号线,4-1、内层线,4-2、外层,5、放射导体,5-1、铜皮,5-2、微带线,6、连接器。
具体实施方式
如图1和图2所示,壳体由可以盖合在一起的上壳体1和下壳体2组成。为方便将本发明安装在车窗玻璃上,在下壳体2的底部固定有不干胶胶片3。信号线4延长出壳体外,与壳体外的连接器6的插头连接。
如图3所示,放射导体5固定在壳体中,放射导体5用信号线4与壳体外的连接器6的插头连接;为提高信号的传输灵敏度,信号线4采用同轴线缆,其内层线4-1为传输信号线连接在放射导体5的微带线5-2上,传输信号线的外层4-2连接在放射导体5的铜皮5-1上做为接地导体。微带线的频率315兆。
