Abstract

The invention discloses multi-mode electronic equipment. A first high-frequency antenna switch is connected with a first antenna, the first antenna comprises a high-frequency antenna portion used for transmitting and receiving high-frequency signals with frequency bands being a first frequency band. A second high-frequency antenna switch and a low-frequency antenna switch are connected with a second antenna through a duplexer, the second high-frequency antenna switch is used for connecting a plurality of high-frequency antennas with frequency bands being a second high-frequency band, and the low-frequency antenna switch is used for connecting a plurality of low-frequency antennas with frequency bands being a first low-frequency band and low-frequency antennas with frequency bands being a second low-frequency band. The second antenna comprises a high-frequency antenna portion and a low-frequency antenna portion, the high-frequency antenna portion is used for receiving high-frequency signals with frequency bands being the second high-frequency band, and the low-frequency antenna portion is used for transmitting and receiving low-frequency signals with frequency bands being the first low-frequency band and the second low-frequency band. The multi-mode electronic equipment saves antenna space and solves the problem that in prior art, due to the fact that each antenna comprises a high-frequency antenna portion and a low-frequency antenna portion, a large antenna space is occupied.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically relates to a multi-mode electronic device. Background technique [0002] A multi-mode electronic device refers to an electronic device that can support multiple network standards, for example, a multi-mode mobile phone that can support WCDMA, CDMA, GSM, and LTE. [0003] A multi-mode electronic device generally includes two antennas, and each antenna includes a high-frequency antenna part and a low-frequency antenna part. Wherein, the first antenna is respectively connected to the first high-frequency antenna switch and the first low-frequency antenna switch through a duplexer, and is used to transmit and receive high-frequency signals whose frequency band is the first high-frequency band and low-frequency signals whose frequency band is the first low-frequency band ; The second antenna is respectively connected to the second high-frequency antenna switch and ...
