The arms of the crossed dipoles are spaced apart from a ground plane. The length of the arms of the crossed dipoles, as well as the height of the array element, is dependent on the lowest wavelength of signal for which the element is to be used with. To adjust the impedance of the antenna array element, a strip of conductive material is used to enclose an area about the arms of the dipoles. A patch component can also be used with the arms being between the patch component and the ground plane. ## Claims ### Claim 1 A dipole antenna comprising: a dipole antenna comprising: a pair of arms extending outwardly from a center and spaced apart from a ground plane, said pair of arms having a combined length ranging from 0.25λ to 0.5λ another pair of arms also extending outwardly from said center and spaced apart from said ground plane: wherein each pair of arms has a combined length ranging from 0.25λ to 0.5λ wherein each pair of arms has a combined length of approximately 0.28λ and said antenna has a height of approximately 0.15λ;
