Multi-slot systems on the base of waveguides with partial dielectric filling

One of the ways of scanning waveguide-slot antennas improvement is their miniaturization and increasing of angle-frequency sensitivity. This problem may be solved using partial filling of a waveguide with dielectric. This gives possibility to slow-down the propagating wave in the waveguide without substantial growing up its weight, to widen the operating band and to increase the angle-frequency sensitivity. All this can be done by the condition that the distance between neighboring slots is less than a half wavelength in a free space. The aim of this work is the studying the possibility of improvement of scanning waveguide-slot antennas characteristics by means of partial filling of the waveguide with dielectric.
