We present a method for matching waveguide radiators used in wide bandwidth phased antenna arrays with wide-scanning angle. In order to achieve matching, the following parameters are used: the geometrical parameters of waveguides, the dielectric parameters of materials inside the waveguides, waveguide transformators and reactive waveguide at the aperture, and ...
