DUAL-POLARIZED ANTENNA

摘要

A dual-polarized antenna may include, but is not limited to, a first ground conductor; a metal patch conductive to the first ground conductor; a dielectric substrate having a first main surface and a second main surface opposite to the first main surface; a second ground conductor disposed on the second main surface of the dielectric substrate, the second ground conductor having at least one of an empty space and a non-empty space of insulator; a first feed probe disposed on the first main surface of the dielectric substrate, the first feed probe being coupled to the metal patch; and a second feed probe being spatially separated by the at least one of the empty space and the non-empty space of insulator from the first feed probe, the second feed probe being coupled to the metal patch through the at least one of the empty space and the non-empty space of insulator.

1. A dual-polarized antenna, comprising:
a first ground conductor having an opening; a metal patch as a radiation element positioned equal to or lower in level in a lamination direction than the first ground conductor, the metal patch being aligned to the opening in the lamination direction; a first feed probe positioned under the first ground conductor in the lamination direction, the first feed probe that excites the metal patch; a second ground conductor positioned below the first feed probe in the lamination direction, the second ground conductor having a slot which is generally parallel to the first feed probe, the slot being positioned under the metal patch in the lamination direction; a second feed probe disposed under the second ground conductor in the lamination direction, the second feed probe being generally perpendicular to the slot, the second feed probe being positioned under the metal patch; and a first dielectric substrate having a first main surface on which the first probe is disposed and a second main surface on which the second ground conductor is disposed.
