Terminal signal transmit-receive device and method

Abstract

The present invention provides a terminal signal transmit-receive device. The device comprises a master antenna and an auxiliary antenna which are used for transmitting and receiving radio frequency signals, a master antenna matching circuit and an auxiliary antenna matching circuit which are respectively connected with the master antenna and the auxiliary antenna, a combiner configured to overlap the signals received by the master antenna and the auxiliary antenna and a power divider configured to distribute signals emitted by the terminals and send the signals to the master antenna and the auxiliary antenna. The auxiliary antenna can effectively improve the transmit-receive performance of signals of a terminal.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a terminal signal transceiving device and a signal transceiving method. Background technique [0002] With the rapid development of science and technology today, terminal electronic products, etc., as people's must-haves in today's life, support more and more frequency band functions. However, as terminal electronic products support more and more functional frequency bands, their shapes are getting thinner and their screens are getting bigger and bigger, and they are on the road to ultra-thin and ultra-large screens, how to improve the receiving and transmitting performance of terminal electronic products is always a challenge. question of inquiry.

However, as the terminal electronic products support more and more functional frequency bands, the appearance is getting thinner and the screen is getting bigger and bigger, and they are on the road to ultra-thin and ultra-large screens, how to improve the receiving and transmitting performance of the terminal electronic products is a constant challenge. question of inquiry

[0003] Taking the mobile phone as an example, at present, by measuring the reception and emission indicators of the mobile phone in a special mode, it can objectively reflect the performance indicators of the mobile phone’s reception and transmission in actual use. Due to the limitation of the shape of the mobile phone, the built-in antenna of the mobile phone mostly uses the flexible circuit board FPC (Flexible Printed Circuit board) and laser antenna LDS (Laser Direct Structuring), and the antenna position is mostly at the bottom of the mobile phone. Usually, when the antenna is at the bottom of the mobile phone, the radiation power and receiving sensitivity of the mobile phone will be found when the head-hand mode test is performed. OTA (Over The Air) performance becomes very poor due to hand model coverage
