Multi-Loop Resonance Structure and Multipe-Input and Multiple-Output (MIMO) Antenna Communication System

A multi-loop resonance structure, wherein the multi-loop resonance structure is disposed along a first dielectric substrate and a second dielectric substrate that are connected perpendicularly;

• and
• the multi-loop resonance structure comprises:
• a metal floor, a first feed branch plate, and a first metal patch, wherein
• the metal floor is disposed on a lower surface of the first dielectric substrate, and the metal floor is provided with a resonant-tank set;
• the first feed branch plate is disposed in parallel on an upper surface of the first dielectric substrate, and a first straight plate in the first feed branch plate is disposed opposite to the resonant-tank set along a substrate line;
• an end, in the first feed branch plate, far away from the substrate line is connected to the metal floor by using an SMA feed connector;
• and the substrate line is a connecting line between the first dielectric substrate and the second dielectric substrate;
• and
• the first metal patch is connected to the metal floor through the first dielectric substrate along a first surface, in the second dielectric substrate, perpendicular to the first dielectric substrate, and the first metal patch is disposed opposite to the resonant-tank set.
