12. A millimeter-wave wideband patch antenna comprising:
a rectangular main patch and two rectangular impedance stabilizing elements each located at a distance from the main patch,
one of the two rectangular impedance stabilizing elements disposed at a first side of the main patch and the other of the two rectangular impedance stabilizing elements disposed at a second side of the main patch opposing said first side, wherein the two impedance stabilizing elements serve to stabilize an impedance of the main patch,
a length of each of the two rectangular impedance stabilizing elements being equal to a length of the main patch, and
a width of each of the two rectangular impedance stabilizing elements being less than half of a width of the main patch,
the main patch comprising:
at least one feed line extending from at least one of a third side and a fourth side of the main patch, and
a row of via extending parallel to at least one of the first side and the second side.
