Abstract
A reflector antenna includes a dual-band waveguide feed and a splashplate support arranged to define a space between the waveguide feed aperture and the splashplate. The dual-band waveguide feed is configured to receive an input signal in a first transmission mode, to convert a transmission mode of an upper frequency band from a first transmission mode to a mixed transmission mode including the first transmission mode and a second transmission mode. The supporting portion can be spaced apart from the aperture of the waveguide feed, and may have a thickness corresponding to half a wavelength of a beam emitted from the aperture.
