Abstract
An S-band antenna with a body having an inner circular tube and a coaxial outer circular tube in which the circumference of the outer tube is one wave length of S-band radar. A plurality of pairs of axially elongated slots are provided in the outer tube in which the slots of each pair are diametrically opposed to each other. Adjacent pairs of slots are axially displaced from each other a distance of one-half wave length. The pairs of slots are rotationally offset at an angle equal to 360/N where N is the number of pairs. A dielectric cover is provided around the outer tube.
