Abstract
A patch antenna includes a metal plate having two parallel long edges and two short edges connected together. The metal plate has a first fold line and a second fold line that are parallel to the two short edges and that partition the metal plate into a ground portion and a radiating portion, the former being longer than the latter but not longer than twice the length of the latter. The metal plate has a shorting portion between the first and second fold lines. A feed-in portion extends from the second fold line toward the first fold line, forms a first slit with the ground portion, and forms a second slit with the shorting portion. Both slits are interconnected. The shorting portion is perpendicular with respect to the ground portion. The radiating portion is perpendicular with respect to the shorting portion and the feed-in portion.
