  • Antenna system and terminal
    Patent number: 9905934
    Abstract: An antenna system includes a first antenna and a second antenna, where the first antenna and the second antenna are connected in parallel to an antenna feeding point, and a phase-shift apparatus is connected in series between the first antenna or the second antenna and the antenna feeding point, so that an imaginary part of impedance at the antenna feeding point is canceled out near a central frequency channel number. The antenna system provides an expansion in radio frequency bandwidth in free space and an increase in average efficiency.
    Type: Grant
