<p>Disclosed is a MIMO antenna, comprising: a PCB, an antenna connected to the PCT, a feed system, and a match circuit. The antenna is connected to the feed system through the match circuit. The antenna connected to the PCB is an antenna having a loopback loop structure, and a ground loop of the antenna connected to the PCB is spaced by a fixed-width gap from the PCB. Also disclosed are a MIMO antenna system and a mobile terminal. The present invention makes a coupling current between the MIMO antenna and the PCB relatively concentrated and makes the current amplitude small, thereby improving the isolation of the antenna.</p> |
