ABSTRACT:
A microwave directional antenna, particularly for the millimeter-wave range, comprises a dielectric line with line discontinuities, affixed to a metallic ground plane. The dielectric line is a radial waveguide extending about a center where the feed is provided. A mode launcher is located at this center. In a preferred embodiment, the boundary of the dielectric line circumscribes a circle; the line discontinuities are preferably embodied as metallic strips arranged on the dielectric guide on circles about the center.
