GTD Analysis of Dual-Polarised Parabolic Cylindrical Reflector Antenna with Diploe Feeds

Dual polarised antenna enable to transmission/reception, or both, of RF in two orthogonal po-larisations. A metallic parabolic cylindrical reflector with dipole feeds at a slant of +45◦ when viewed from the front acts as a dual polarised antenna. This antenna is analyzed using geometrical theory of diffraction (GTD) technique. Vertically and horizontal polarized far-field electric field are computed and plotted for radiation pattern.
