  • Patent number: 10535916
    Abstract: The present invention relates to a watch-type mobile terminal, comprising: a main body; a first band and a second band which are connected one side and the other side of the main body; a main board located inside the main body; a first antenna module mounted on the first band and connected to the main board to transmit and receive wireless signals; a second antenna module mounted on the second band and connected to the main board to transmit and receive wireless signals; and a control unit for maintaining the connection state between the second antenna and the main board when wireless communication is performed through the first antenna module, thereby using the second antenna module as the ground of the first antenna module. The watch-type mobile terminal can enhance the efficiency of the antennas by minimizing interferences among a plurality of antennas.

  • Patent number: 7522106
    Abstract: An antenna having an extended operation frequency bandwidth that includes: a feed, and a plurality of radiators which are connected to the feed to receive current and divided at the feed. Accordingly, the RFID radio signals and the mobile communication radio signals can be transmitted and received via the single antenna because the frequency bandwidth is expanded. Therefore, the efficiency of the antenna can be improved and the mobile communication terminal can be miniaturized. Furthermore, since the antenna obtains the increased gain, the communication quality of the antenna can be enhanced and the power consumption can be reduced.
