Abstract
Dielectric strips made of a dielectric material are placed between a pair of conductor plates located a specified distance apart. Cutouts are formed in the dielectric strips. The cutouts, a part of each dielectric strip is formed into an electrically asymmetric portion. When high-frequency power is supplied to the dielectric strips, the power is transmitted through an NRD waveguide composed of the dielectric strips and the pair of conductor plates, with the result that electromagnetic wave is radiated from the cutouts into the space between the conductor plates. This electromagnetic wave excites the radiation elements formed in the conductor plates, which then radiate electromagnetic waves.
