Title: RADAR RADIATION REDIRECTING TAPE
Abstract:
Radar radiation redirecting tapes (1, 2) include a first plurality of individual radar-reflecting directional antennae (5, 11). Each directional antenna comprises at least three elongate, unevenly spaced antenna conductors (10, 20, 30), arranged with their long extensions parallel to each other in the plane of the tape, such that the directional antenna is operable to reflect incoming radar radiation predominantly in a direction (80) which is orthogonal to the long extension of the antenna conductors and parallel to the plane of the tape.
