Abstract (en)
A dual frequency band antenna (10) having frequency reuse capability. The antenna waveguide (12) includes a four port waveguide network which transmits and receives orthogonal, linearly polarized signals of each of two frequencies. A pyramidal horn (14) is engaged to the mouth of the waveguide, and a meanderline polarizer (16) is engaged to the aperture (17) of the horn (14) to convert the signals from linear polarizations to circular polarizations. <IMAGE>
