DIELECTRIC LEAK WAVE ANTENNA HAVING MONO-LAYER STRUCTURE

摘要

A dielectric leak wave antenna having a monolayer structure effective in realizing a highly efficient sub-millimetric wave band antenna at low cost. The dielectric leak wave antenna comprises a ground plate conductor, a dielectric substrate placed in close contact with one side of the ground plate conductor and forming a transmission path for transmitting electromagnetic wave to/from the ground plate conductor along the surface from one end to the other, bodies adapted for leaking electromagnetic wave from the surface of the dielectric substrate and mounted on the surface thereof, at predetermined intervals, in such a direction that the electromagnetic wave is transmitted through the transmission path, and a power supply section for supplying electromagnetic wave to the one end of the transmission path.
