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 an insulating area, one end of the second surface adjacent to the insulating area defining a first isolating area and a second isolating area spaced from each other, a horizontal feed circuit and a vertical feed circuit being disposed at the one end of the second surface and beside 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 insulating area being exposed outside, and a second ground plane which is covered on the second surface of the insulating substrate with the first and second isolating areas being exposed outside and is further electrically connected with the first ground plane; a radiating element located onto the insulating area of the insulating substrate; and a horizontal feed probe and a vertical feed probe inserted in the insulating substrate and the radiating element with one end thereof projecting beyond the radiating element and the other end thereof respectively penetrating through the first isolating area and the second isolating area so as to couple with the horizontal feed circuit and the vertical feed circuit, respectively.
