In the reflector-based compact antenna test range (CATR), the aperture usage is one of our most concerned problems. Higher aperture usage means that in a CATR with the same aperture reflector, a ...

An Ultra Wideband (UWB) parabolic reflector horn antenna system is designed to cover frequency range from 2 GHz to 18 GHz. The feed structure is redesigned for the ridged horn antenna to overcome the ...

To get that JWST look, the build has 18 mirrors assembled on a 3D printed frame to approximate the shape of a larger parabolic reflector.
