    摘要： An array antenna is provided that operates at high-band and low-band, comprising a first array of high-band radiators and a second array of low-band radiators, each respective low-band radiator disposed so as to be interleaved between the high-band radiators so as to share an aperture with the high-band radiators. Each low-band radiator comprises a coaxial section, a dielectric section, a waveguide, and a planar section. The dielectric section is formed of a continuous piece of dielectric material and includes a hollow opening formed perpendicular to the coaxial section, and a plurality of step transitions, wherein at least one of the step transitions is disposed within and partially fills the waveguide operably coupled to the planar section. The planar section is oriented to the portion of high-band radiators such that the output of the respective low-band radiator is disposed between and within the spacing between adjacent high-band-radiators.

    摘要： A dual reflector antenna system includes a subreflector and a main reflector with optimized shapes defined from a desired field distribution pattern and a feed pattern. The reflector shapes capture maximum energy from the feed and allow sidelobes to closely track a predetermined sidelobe envelope for optimal overall antenna efficiency.
