与天线结合的导航系统
摘要：
一种与天线结合的导航系统，其包括一由电镀盒体(3)和盖罩(4)构成的匣盒(2)。天线元件(10)集成到匣盒(2)上，并与作为天线元件(10)的接地端的盖罩(4)电连接。通过这种构造，匣盒(2)和天线元件(10)可以立即一次性地安装在车辆上，并且消除了匣盒(2)外面的天线元件(10)的布线。因此，与现有设备相比，提高了导航系统(1)的安装性能。而且，盖罩(4)以其表面比天线元件(10)的表面大的方式形成。因此，天线的方向性可以得到完全保证。
摘要（英）：

A navigation system incorporating an antenna includes a cabinet constructed of electroplated case and cover. An antenna element is integrated to the cabinet and electrically connected with the cover that is a ground of the antenna element. With this configuration, the cabinet and the antenna element can be installed in a vehicle at once and wiring of the antenna element outside the cabinet can beeliminated. Thus, installability of the navigation system is improved in comparison with known devices. Furthermore, the cover is formed such that its surface is larger than that of the antenna element. As a result, directivity of the antenna element is properly secured.
