An antenna array comprising a ground plane and a plurality of elements mounted
thereon, said elements being capable of emitting and receiving ultra wideband emissions.
Elements are arrayed on the ground plane in two parallel rows, a transmitting row,
and a receiving row, such that a given element in the receiving row is aligned
in at least one direction with a corresponding element in the transmitting row.
Additionally, the elements are configured on the ground plane to elicit a symmetrical
product response in the azimuthal plane, and to produce horizontally polarized
signals. An alternative embodiment places the elements with unique inter-element
spacing within the rows. An embodiment comprises a fence structure between rows.
A method for use comprises the step of transmitting a signal via an element in
the transmitting row and receiving said signal through an element in the receiving
row, not aligned with the transmitting element.
