CONSTITUTION: A balun coupler(410) receives one input signal for distributing the input signal as two outputs equal in power and different in phase at an angle of 180 deg. A saturation magnetostatic wave filter(420) receives one signal among two output signals from the balun coupler for converting the same to magnetostatic wave and inversely converting the magnetostatic wave, and saturates input power over a noise level. A linear magnetostatic wave filter(430) receives the other signal among two output signals from the balun coupler for converting the same to magnetostatic wave and inversely converting the magnetostatic wave, and converts input power into magnetostatic wave by linear energy. A power synthesizer(440) synthesizes signals output from the saturation magnetostatic wave filter and the linear magnetostatic wave filter.

Abstract: PURPOSE: An antenna apparatus is provided to produce a desired multiple beam pattern without controlling the signal and the phase of each antenna device. CONSTITUTION: A first ridge horn antenna and a second ridge horn antenna have a third mode beam pattern for restraining directivity. The second ridge horn antenna is separated from the first ridge horn antenna with a gap. A multiple beam pattern is produced by using the third mode beam pattern of the first and the second ridge horn antenna. The gap is obtained by changing the phase difference between the angle of a progressive wave and an antenna device. The gap is twelve times smaller than the half wavelength of operating frequency.
