Abstract

The invention provides a compact MIMO antenna and a communication device comprising the same. The compact MIMO antenna comprises a neutralization line and two antenna elements, namely a first antennaelement and a second antenna element. The first antenna unit and the second antenna unit are connected through a neutralization line, and the neutralization line includes at least one L-shaped bent portion; the antenna unit includes a trapezoidal radiation body, a ground point connected to the GND, and a feed point for transmitting a signal. The long bottom edge of the trapezoidal radiation body is far away from the GND setting; The long bevel edge of the trapezoidal radiation body is arranged close to the neutralization line; The first end of the long bottom side of the trapezoidal radiationbody is connected to the neutralization line, and the second end of the long bottom side of the trapezoidal radiation body extends with a radiation end, the end point of the radiation end is close tothe GND and is provided with a gap with the GND. The invention meets the requirements of small size, high isolation, simplified structure, high signal transmission performance and good anti-interference performance of the MIMO antenna.

Description

technical field [0001] The invention relates to the technical field of MIMO antennas, in particular to a compact MIMO antenna and communication equipment including the same. Background technique [0002] With the increasing demand for high-performance wireless communication, MIMO (Multiple-input Multiple-output)) technology emerges at the historic moment and has received widespread attention. MIMO technology uses multiple antennas to achieve multiple transmissions and multiple receptions, which greatly improves the channel capacity and spectrum utilization of communication equipment without increasing the antenna transmission power and bandwidth. [0003] The key points of MIMO antennas are the isolation between the antennas and the size of the antennas. The MIMO antenna needs to maintain a certain degree of isolation between the antennas to achieve better performance, and improving the isolation generally requires a larger distance between the antennas, which will result i...
