Abstract:
A low profile broad band antenna, comprising a first conductive plate having a first length and first width, the first conductive plate having opposite first and second ends;a second conductive plate having a second length that is greater than said first conductive plate first length and a second width that does not exceed the first conductive plate first width, the second conductive plate also having opposite first and second ends; the first ends of said first and second conductive plates being aligned with each other; a shorting plate interconnecting said first and second conductive plates together the shorting plate having a width that is less than said first and second conductive plate widths, the shorting plate extending in a plane transverse to said first and second conductive plates alongside said first ends of said first and second conductive plates; a feed plate having a predetermined length and width and interposed between said first and second conductive plates, the feed plate having opposed first and second edges, said feed plate width being equal to the widths of said first and second conductive plates, said feed plate being disposed such that said first edge is spaced apart from said shorting plate and said second conductive plate, and said first plate second edge being aligned with said feed plate second edge so as not to exceed said feed plate second edge; a feed connector to said antenna, a center conductor of said antenna, a center conductor of said feed connector extending through said second plate and terminated in said feed plate and a ground conductor of said feed connector being terminated to said second plate.
