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.

Abstract: Embodiments disclose a radio frequency front-end system and a signal transmission control method. The system includes a first antenna, a second antenna, a first radio frequency circuit, a second radio frequency circuit, and a controller. The controller is configured to acquire a transmission frequency band selected by the first radio frequency circuit, and when a frequency in the transmission frequency band selected by the first radio frequency circuit is less than a preset frequency, to control the first radio frequency circuit to connect to the second antenna. The controller is further configured to disconnect a connection between the second radio frequency circuit and the second antenna, or to maintain an open circuit state between the second radio frequency circuit and the second antenna.
