Patent ID: 8878742

Claim:
A linearly polarized dipole antenna with an unbalanced microstrip feed comprising: a substrate having a top surface and a back surface; a microstrip feed line in contact with said back surface of said substrate, said microstrip feed line having an input end for accepting an electrical signal; a ground plane having a top surface and a back surface, wherein said back surface of said ground plane is in contact with at least a portion of said top surface of said substrate, said ground plane further having a ground plane aperture in said top surface of said ground plane that exposes at least a portion of said substrate; a conductive first dipole element having a first vertical stem and a first horizontal arm, wherein a first end of said first dipole element extends through said ground plane aperture through said substrate and contacts said microstrip feed line; and a conductive second dipole element having a second vertical stem and a second horizontal arm, wherein said second vertical stem is spaced a gap distance, g, apart from said first vertical stem, and further wherein a first end of said second dipole element extends through said ground plane aperture through said substrate and is connected to said back surface of said substrate.
