  • Publication number: 20110273340
    Abstract: An antenna device for a mobile terminal is provided. The antenna device is adapted for digital broadcast reception. The mobile terminal is composed of a front case, a rear case, a battery cover, a main board and a feed supplying power on the main board. The mobile terminal includes a first antenna, electrically connected to the feed, for receiving electric current from the feed to receive a digital broadcast signal, and a second antenna, electrically connected to the feed and installed separately from the first antenna, for receiving electric current from the feed to receive a digital broadcast signal. The first antenna and the second antenna are used for antenna matching and bandwidth maintenance during digital broadcast reception. Hence, reception performance of digital broadcast signals can be improved.
