Novel compensation method for electromagnetic performance of dielectric radome based on reflector shaping

From the viewpoint of geometrical optics, dielectric radome degrades the electromagnetic performance of the enclosed antenna by distorting the amplitude distribution and phase distribution of aperture field, of which the latter is mainly responsible for the distortion of far-field pattern. A novel m...
