Abstract
A primary radiator comprises a base part in an upper surface of which a groove having a width of ½ to {fraction (1/1)} of the signal wavelength of a high frequency signal and a depth of about ¼ of the signal wavelength is formed as a waveguide for the high frequency signal, and a moving part which is placed in such a manner as to cover the groove, and which includes a coupling window for an electromagnetic wave of the high frequency signal and a reflecting member that is formed on a lower surface of the moving part in such a manner as to fit in a cross section of the groove and is positioned away from the coupling window by ⅛ to {fraction (1/1)} of the guide wavelength of the high frequency signal.
