Research of dielectric radiators for phased antenna arrays

The results of development and experimental research of waveguide-dielectric radiators for flat multielement phased antenna arrays for Ka and W frequency bands are submitted. The Ka-band radiators are intended for phased antenna array with wide sector of beam scanning /spl plusmn/45/spl deg/. The W-band radiators used in elements of phased antenna array with the cross section sizes less than 1,25/spl lambda/ (/spl lambda/ - is wavelength), have the far field pattern considering mutual coupling of antenna array elements, which allows a /spl plusmn/15/spl deg/ beam scanning.
