As described above, in the conventional mobile communication device, the antenna and the substrate are electrically connected via the holder base. In this case, the holder base is fitted to the housing. Therefore, the volume must be large and the capacity must be large, and the holder base having the large capacity degrades the antenna gain. Since the base needs to be made of metal, the weight increases, and since the holder base and the substrate are electrically connected by spring-type contacts, there are restrictions on the dimensions of the holder base and the spring-type contacts. The distance between the board and the antenna cannot be freely set.

The present invention has been made to solve such a problem, and can improve the antenna gain, reduce the weight, and freely set the distance between the substrate and the antenna. It is intended to provide a mobile communication device having an antenna configuration that can be used.

In this case, since the spring holder also serves as a feeding point, power can be fed without passing through a large-capacity holder base, so that the antenna gain can be improved, and the holder base does not need to be made of metal. Since notches are also provided, the weight can be reduced, and the spring holder and the board are electrically connected through an antenna mounting bracket having a large degree of freedom in dimension and shape.
The distance between the substrate and the antenna can be set freely.

Further, the mobile communication device of the present invention comprises a telescopic antenna held by a housing via a holder, an antenna mounting bracket for fixing the telescopic antenna to the housing via the holder, In a mobile communication device having an antenna configuration including a spring-type contact mounted on a substrate for electrically connecting the extendable antenna to a substrate, the holder may be configured to expose a feeding point and the housing And a spring base for holding the telescopic antenna, and a spring holder serving as the power feeding point and fixing the spring to the holder base. The telescopic antenna is electrically connected to the substrate by making contact with the spring-type contact. With this configuration, the telescopic antenna is electrically connected to the substrate via the spring, the spring holder, the antenna mounting bracket, and the spring contact. In this case, since the spring holder also serves as a feeding point, power can be fed without passing through a large-capacity holder base, so that the antenna gain can be improved, and the holder base does not need to be made of metal. Notches are provided to reduce the weight, and the distance between the substrate and the antenna can be freely set because the spring holder and the substrate are electrically connected via the antenna mounting bracket having a large degree of freedom in dimension and shape. Can be set to

The holder base is preferably made of resin.
By doing so, the weight can be reduced.
