    摘要： PURPOSE:To obtain easily switchingly a radiation pattern of the full directivity and the selected directivity, by taking two antennas having the directivity of the same direction each as a couple, arranging antennas so as to make the directivity of each couple orthogonal and controlling a signal impressed to each antenna. CONSTITUTION:Four slot antennas 901-904 of which the center point of radio wave irradiation is located on a straight line and having the directivity of butterfly-fugure are arranged on a metallic conductor on a dielectric so as to make the directivity of each couple of the antennas 901 and 904, and 902 and 903 orthogonal with each other. Further, the distance between the center point of radio wave irradiation of the antenna elements of each couple is taken as (2n+1)lambda/4 and lambda/2, and a signal having the (2n+1)pi/2 of phase difference is impressed to the couple of the antennas 901, 904 from a phase shifter 905 and a signal having pi of phase difference is impressed to the couple of the antennas 902, 903 from a phase shifter 906. Further, a signal of pi/2 of phase difference is impressed switchingly to the antennas 903, 904.

    摘要： PURPOSE:To cover a specific district effectively with plural beams, by providing two reflecting mirrors in which the plane of polarization of reflected elecromagnetic waves is orthogonal with each other and exciting horns to adjacent beams with the orthogonally polarized waves. CONSTITUTION:A reflecting mirror is constituted of reflecting mirrors 1a, 1b reflecting electromagnetic waves whose plane of polarization is orthogonal with each other, the horns 2a, 2c are excited by using the reflecting mirror 1a and the horns 2b, 2d are exited by using the reflecting mirror 1b. A primary radiator 3a consists of the horns 2a, 2c and a primary radiator 3b comprises the horns 2b, 2d and the primary radiators 3a, 3b are used with orthogonally polarized waves each other. The beams 4a'-4d' are the beams irradiated from the horns 2a-2d respectively.
