Abstract

The invention discloses a difference dual-port ultra wideband MIMO antenna. The difference dual-port ultra wideband MIMO antenna comprises a dielectric substrate and further comprises a difference port A, a difference port B and a metal ground, wherein the difference port A and the difference port B are arranged on the front face of the dielectric substrate, and the metal ground is arranged on the back face of the dielectric substrate. The hollow portion of the metal ground is a wide gap. The difference port A and the difference port B are mutually orthogonal. The difference dual-port ultra wideband MIMO antenna has the advantages of being high in isolation degree, compact in structure and ultra-wide in working bandwidth, and can meet the requirements for miniaturization, low cost, easy integration with a difference circuit.

Description

technical field [0001] The invention relates to a differential ultra-wideband MOMO antenna, in particular to a differential dual-port ultra-wideband MIMO antenna. Background technique [0002] With the rapid development of wireless communication technology, communication systems have increasingly strong demands for high-speed, large-capacity, and high-reliability mobile communication quality, but it is difficult to meet this demand with traditional communication technologies. Multiple-input-multiple-output (MIMO) technology uses multiple transceiver antennas to transmit and receive signals in a communication system, which can effectively overcome multipath fading effects and improve system capacity and reliability. In the design of MIMO antennas, one of the most critical issues is how to reduce the coupling between the various antenna elements. At present, the main methods to reduce the coupling between antenna units are: EBG floor structure, decoupling network, floor gap, ...
