Abstract

The invention discloses an electronic device. The electronic device comprises: a transceiver; a first antenna, a second antenna, a third antenna and a fourth antenna; and a first radio frequency circuit, a second radio frequency circuit, a third radio frequency circuit, a fourth radio frequency circuit. According to the invention, the first antenna and the second antenna are used in the electronicdevice to carry out frequency division multiplexing transmission on the emission signals and the main set reception signals of the two frequency bands respectively; meanwhile, the other two antennasare respectively used for transmitting the diversity receiving signals of the two frequency bands, so that the antenna for transmitting the transmitting signal and the main set receiving signal is prevented from transmitting the diversity receiving signal at the same time, the number of signals transmitted by the antenna is reduced, the antenna is enabled to transmit signals of at most two signalfrequencies at the same time, and the transmission performance of the antenna in the signal transmission process in the electronic equipment is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an electronic device. Background technique [0002] In order to achieve compatibility between 4G and 5G in mobile phones and other devices, the antenna for signal transmission needs to support two frequency bands. At the same time, in order to achieve frequency division duplexing, the antenna needs to transmit the uplink signal and the downlink signal together. Therefore, the antenna needs To support sending and receiving two different frequency signals in the same frequency band at the same time, it is also necessary to support receiving a signal in another frequency band. [0003] Although the antenna itself has a certain bandwidth, one antenna needs to simultaneously transmit signals of three frequencies, which will make the transmission performance of the antenna on each frequency poor. Contents of the invention [0004] In view of this, the applicatio...
