Ultra wide band antenna element

摘要

Antenna unit cells suitable for use in antenna arrays are disclosed, as are antenna array and mounting platform such as an aircraft comprising antenna unit cells. In one embodiment, an antenna unit cell comprises a dielectric substrate having a length extending along a first axis and a width extending along a second axis, a first plurality of radiating elements disposed on a first side of the dielectric substrate, and a second plurality of radiating elements disposed on a second side of the dielectric substrate, opposite the first side. In some embodiments the first plurality of radiating elements extend to an edge of the unit cell, and the second plurality of radiating elements overlap portions of the first plurality of radiating elements. Other embodiments may be described.
