Abstract

The invention relates to an antenna system and a mobile terminal. The antenna system comprises a main set radio frequency front-end module, a diversity radio frequency front-end module, a first antenna and a second antenna. The main set radio frequency front-end module and the diversity radio frequency front-end module are connected with the first antenna and the second antenna respectively; or the main set radio frequency front-end module and the diversity radio frequency front-end module are connected with the second antenna and the first antenna respectively. The main set radio frequency front-end module is provided with N main set antenna ports, wherein the N main set antenna ports are connected with the first antenna or the second antenna simultaneously, N being a natural number, N>1. Besides, one of the main set antenna ports is used for transmitting main set signals at a first frequency band, and the first frequency band is higher than frequency bands of main set signals transmitted by the other main set antenna ports. The antenna system can reduce high-frequency insertion loss; and since the high-frequency insertion loss is larger than low-frequency insertion loss, insertion loss of the antenna system under a multi-band application scene is reduced on the whole.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna system and a mobile terminal. Background technique [0002] Diversity Techniques is the use of multiple signal paths that transmit the same information and have approximately equal average signal strength and independent fading characteristics, and properly combine these signals at the receiving end to greatly reduce the impact of multipath fading. The reliability of transmission is thereby improved. [0003] A traditional antenna system using diversity technology usually includes two antennas, a main radio frequency front-end module and a diversity radio frequency front-end module. Wherein, the antenna connected to the main radio frequency front-end module is a main radio antenna, and the antenna connected to the diversity radio frequency front-end module is a diversity antenna. The main set antenna is responsible for sending and receiving radio frequency s...
