DIELECTRIC LEAK WAVE ANTENNA HAVING MONO-LAYER STRUCTURE

摘要

The present invention provides a dielectric leaky-wave antenna having a single-layer structure which is effective for realizing a highly efficient low-cost antenna in a quasi-millimeter wave zone in particular. This dielectric leaky-wave antenna includes a ground plane, a dielectric slab which is laid on one surface of the ground plane and forms a transmission guide for transmitting an electromagnetic wave from one end side to the other end side between itself and the ground plane along the surface, perturbations which are loaded on the surface of the dielectric slab along the electromagnetic wave transmission direction of the transmission guide at predetermined intervals and leak the electromagnetic wave from the surface of the dielectric slab, and a feed which supplies the electromagnetic wave to one end side of the transmission guide.
