Abstract (en)
[origin: WO9317466A1] A dual band signal receiver (10) is provided with relatively coaxial antenna assemblies (12, 11) electromagnetically coupled to respective upper and lower band rectangular waveguides and ports through suitable polarization switching assemblies. The upper band rotatable antenna assembly (12) consists of a dipole feed (14) having driven dipole element (16), parasitic dipole elements (17), and a corner reflector element (70) electromagnetically coupled to the upper band rectangular waveguide by a suitable transmission line extending substantially along the longitudinal axis or centerline of the lower band cylindrical waveguide.
