Abstract
An antenna feeder line of the invention comprises a dielectric substrate, a first main conductor layer, a second main conductor layer, through conductor groups in two rows and sub conductor layers, which form a dielectric waveguide line, wherein a slot is provided in the first main conductor layer of the dielectric waveguide line, high-frequency signals are fed to an antenna device disposed above the slot, and a grounding conductor comprising a conducting bar and/or a conductor layer, for electrically connecting the first and second surfaces constituting H surfaces is disposed in a position which is perpendicular to a signal transmission direction and at a distance substantially not more than ½ the distance between E surfaces from side surfaces constituting the E surfaces, in a transmission area within a distance substantially the same as the signal wavelength from the slot to the input side or the side opposite thereto.
