Abstract: A board includes: a baseband unit, multiple transmitters, multiple receivers, a multi-antenna array, a correction transceiver, a correction calculation unit, a bidirectional coupler, and a combiner-splitter. The bidirectional coupler is configured to couple radio frequency signals output by the multiple transmitters and then transmit the coupled radio frequency signals to the combiner-splitter, and to couple receiver correction reference signals obtained by performing division by the combiner-splitter and then send the coupled receiver correction reference signals to the multiple receivers; and the combiner-splitter is configured to combine transmitter radio frequency signals coupled by the bidirectional coupler and then transmit the combined transmitter radio frequency signals to the correction transceiver, and to divide a receiver correction reference signal sent by the correction transceiver and then send receiver correction reference signals obtained by performing division to the coupler. Accuracy of channel reciprocity correction of a transmitter and a receiver can be ensured.

Abstract: This application discloses an antenna system, includes: a ground plate, at least one antenna pair disposed on the ground plate, and a decoupling assembly disposed on a radiation surface of the antenna pair; where the antenna pair includes a first antenna and a second antenna; the decoupling assembly is configured to adjust antenna radiation directions of the first antenna and the second antenna. In this application, the following problem is resolved: A poor effect is achieved when coupling between antennas is reduced by using a slit because there are many electronic elements in a mobile terminal and the slit is easily affected by surrounding electronic elements. Antenna radiation directions of the antennas are changed by using the decoupling assembly disposed on the radiation surface of the antenna pair, thereby improving isolation between the antennas and antenna radiation efficiency.
