All ArchivesMatching waveguide radiators in antenna arrays with broadband and wide-angle scanningWe 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 ...

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.

Numerical results and measurements of broadband microstrip radiators of the phased antenna arrays characteristics are presented. The obtained results can be used at designing the flat phased antenna arrays containing longitudinal printed radiators.
