Antenna structure for MIMO application

摘要

An antenna structure for MIMO application includes a substrate, a first antenna element, and a second antenna element. A metal ground layer covers a portion of a first surface of the substrate, and the first antenna element is arranged on the metal ground layer. The first antenna element includes an open-slot, which extending from an edge of the metal ground layer toward an inner portion of the metal ground layer, and a signal feed-in member arranged on a second surface of the substrate and spatially corresponding to an open end of the open-slot. The second antenna element is arranged on the first surface of the substrate adjacent to the first antenna element and extending away from the metal ground layer, and includes a signal feed-in portion arranged adjacent to the open end of the open-slot, and electronically connects to the signal feed-in member.

主权项

1. 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; anda 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; anda signal radiation portion extending along the open-slot from the signal feed-in portion toward a direction away from the metal ground layer.
