摘要： PURPOSE:To attain miniaturization by bonding a signal output square waveguide to a side face of a circular waveguide facing a dielectric plate so as to extract an output thereby reducing the length of the circular waveguide with respect to the primary radiator in common use for vertical and horizontal polarized waves. CONSTITUTION:A dielectric plate 3 turnable around a guide axis of a circular waveguide 2 is provided in the inside of the circular waveguide 2 in which one end is used for an opening 1 to receive an electromagnetic wave and the other end is used for a termination face 5, a square waveguide 4 is bonded to a side face of the circular waveguide 2 facing the dielectric plate 3 and the length of the dielectric plate 3 in the lengthwise direction is selected to be a length at which a phase difference between two polarized wave components orthogonal to each other of the electromagnetic wave in the TE11 mode is to be 180 deg..

摘要： PURPOSE:To obtain a primary radiator to be shared with circularly polarized waves(CPWs) and linearly polarized waves(LPWs) (horizontal/vertical PWs) which can receive both radio waves of CPWs and LPWs from a satellite using both CPWs and LPWs. CONSTITUTION:The 1st phase circuit (metallic blocks 3, 4), the 2nd rotary phase circuit (dielectric plate 7) and plural output means (square waveguides 9, 10) respectively corresponding to rectangular components in a TE11 mode radio wave are successively arranged in the direction from the aperture part (1) side of a circular waveguide 2 to its terminal end face 5. In the case of receiving a CPW, the CPW is converted into an LPW by the 1st phase circuit, the plate 7 is turned so that the phases of the rectagular components in the LPW are not differentiated and a signal is outputted from one output means. In the case of receiving an LPW, a phase difference between the rectangular components in the LPW which is generated by the 1st phase circuit is eliminated so as to be inphase by rotating the plate 7 and one signal in the LPW is outputted from the other output terminal, while rotating the plate 7 so that the phase difference is about 180 deg. and outputting the other signal in the LPW from the other means.

摘要： PURPOSE:To decrease the-heating and to miniaturize the switch by placing a cylindrical magnet coaxially with a ferrite bar of the center and coupling it with a magnetic yoke on both ends, magnetizing it by a pulse current allowed to flow to a coil, and also, switching the plane of polarization by the control of the pulse current. CONSTITUTION:A cylindrical magnet 22 is provided coaxially with a coil 20 and a ferrite bar, and inserted and held, and fixed by magnetic yokes 24, 26 on both its ends. When a pulse current is allowed to flow to the coil 20 in the direction as shown in the figure, the cylindrical ferrite magnet 22 is magnetized, and even if a current is not allowed to flow continuously, a magnetic field is applied to the ferrite bar 10 from the ferrite magnet 22. In the case of switching the plane of polarization, it will suffice that the pulse current is allowed to flow in the reverse direction. In such a way, the polarization plane switch of a structure which is scarcely heated and suitable for miniaturization can be obtained.
