Abstract
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 interelement 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.

52. A method for using an antenna array, said antenna array being comprised of a row of transmitting antenna elements and a row of receiving antenna elements parallel to said row of transmitting antenna elements, said receiving antenna elements being arrayed such that any receiving antenna element comprising said row of receiving antenna elements is aligned with a corresponding transmitting antenna element in a plane perpendicular to said transmitting and receiving rows and a means for controlling signal emission from each transmitting antenna element and signal reception to each receiving antenna element, comprising the steps of:
-
a. emitting a signal from at least one transmitting antenna element; and
b. receiving said signal by at least one non-corresponding receiving antenna element. - View Dependent Claims (53)
