Abstract:
A low-profile monopole antenna structure having a linear polarization, comprising:a first metallic patch and a second metallic patch stacked over a ground plane, the first patch comprising a circumference along a patch edge of the first patch, the second patch comprising a circumference along a patch edge of the second patch, the first patch being arranged between the ground plane and the second patch, the first patch being grounded at at least a first zero potential area by electrical connection with the ground plane and a second zero potential area by electrical connection with the ground plane, and has been inserted after â€œandâ€  second being fed at a single feed area, the second patch being electrically interconnected to the first patch, and the first patch comprises at least a first aperture and a second aperture located completely within the circumference of the first patch to thereby force currents, propagating from the feed area to the first zero potential area and the second zero potential area, toward the patch edge of the first patch to thereby enable radiation from slots defined by the edge of the first patch and the edge of the second patch and the ground plane.
