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 ...

It is presented the electrodynamics analysis of complex cross-section waveguide phased-array antennas with dual polarization. Energetic, polarization and frequency characteristics of cross-ridged circular and square waveguides as elements in phased-array antennas with dielectric covers and supports are studied. An analysis chart is introduced to aid the computation of their mode of operation with sector scanning and frequency band. Antennas
