Multi-element omni-directional antenna

摘要

An antenna circuit board assembly comprises a substrate having a ground plane comprised of a conductive material; a first antenna element mounted to the substrate and coupled to the ground plane; a second antenna element mounted to the substrate and coupled to the ground plane; a third antenna element mounted to the substrate and coupled to the ground plane; and a plurality of features etched into the ground plane, each of the plurality of features having a respective length and a respective width. The respective length and the respective width of each of the plurality of features are selected to increase isolation between the first, second, and third antenna elements.

1. An antenna assembly comprising:
a circuit board; a ground plane embedded in the circuit board and comprised of a conductive material, the ground plane comprising a plurality of curved features etched into the ground plane, each of the curved features including a respective curved portion that is without a linear segment as the respective curved portion curves from a corresponding first point to a corresponding second point; and a plurality of antenna elements, each of the plurality of antenna elements mounted to the circuit board and coupled to the ground plane; wherein each of the plurality of curved features etched into the ground plane is dimensioned to increase isolation between the plurality of antenna elements; wherein the ground plane has an outer edge that defines a perimeter of the ground plane, each of the curved features including an open-ended slot that extends into the ground plane from the outer edge, the open-ended slots being open along the outer edge.
