Abstract:
1. An antenna device, comprising: an insulating substrate having a first surface and a second surface opposite to the first surface, one end of the first surface defining a first isolating area and a second isolating area spaced from each other, one end of the second surface adjacent to the first isolating area and the second isolating area defining an insulating area, a horizontal feed circuit and a vertical feed circuit being disposed at the insulating area and spaced from each other corresponding to the first isolating area and the second isolating area respectively; a ground plane including a first ground plane which is covered on the first surface of the insulating substrate with the first and second isolating areas exposed outside, and a second ground plane which is covered on the second surface of the insulating substrate with the insulating area exposed outside and is further electrically connected with the first ground plane; a radiating element positioned opposite to and spaced from the first ground plane by means of the support of a plurality of mounting pillars which are inserted in the insulating substrate and projected beyond the first ground plane; and a horizontal polarized portion and a vertical polarized portion positioned on positions of the radiating element corresponding to the first and second isolating areas respectively and spaced from each other, so as to couple with the horizontal feed circuit and the vertical feed circuit, respectively.
