ABSTRACT:
A leakage dielectric waveguide includes a housing made of plane-shaped electrical conductors located parallel to each other, and a dielectric strip for propagating a high-frequency wave between the parallel electrical conductors, wherein the dielectric strip is provided within the housing. The housing is arranged to be asymmetrical, thereby leaking and radiating a high-frequency wave propagating through the dielectric strip. The housing is preferably further composed of the plane-shaped parallel electrical conductors and a side wall. A plane antenna includes the above-mentioned leakage dielectric waveguide, and a projecting device for projecting the high-frequency wave toward a free space in response to a high-frequency wave being projected from the dielectric waveguide. Alternately, a plane antenna includes a plurality of the above-mentioned leakage dielectric waveguides, and a projecting device for projecting either one high-frequency wave or a plurality of high-frequency waves toward a free space in response to a plurality of high-frequency waves being projected from the plurality of dielectric waveguides.
