Antenna structure for mimo application

An antenna structure for MIMO application, the antenna structure comprising:

• at least one substrate comprising a first surface and a second surface opposite to the first surface;
• a metal ground layer covering a portion of the first surface of the substrate;
• a first antenna element arranged on the metal ground layer, the first antenna element comprising:
• an open-slot extending from an edge of the metal ground layer toward an inner portion of the metal ground layer, wherein the open-slot is open at one end adjacent to the edge and closed at the other end at the inner portion;
• and
• a signal feed-in member arranged on the second surface of the substrate and spatially corresponding to the open end of the open-slot, with opposite end portions thereof being mounted on the substrate and respectively spatially corresponding to portions of the metal ground layer on opposite sides of the open-slot;
• and
• a second antenna element arranged on the first surface adjacent to the first antenna element and extending away from the metal ground layer, the second antenna element comprising:
• a signal feed-in portion arranged adjacent to the open end of the open-slot and electronically connected to the signal feed-in member;
• and
• a signal radiation portion extending along the open-slot from the signal feed-in portion toward a direction away from the metal ground layer.
