Abstract
Substantial weight reduction and size reduction in phased array radiators are obtained by coupling a dielectrically loaded waveguide directly to a short horn radiator whose electrical length is less than one half wavelength at an operating frequency. Coupling is obtained by positioning the waveguide with its end in the interior of the short horn radiator and by causing the dielectric material of the waveguide to protrude beyond the end of the waveguide and to terminate inside the horn.
