PURPOSE:To enable to constitute an antenna with the same type of coupler, bent waveguide and waveguides, by providing two delay lines at both the sides of a radiator with one stage shifted and feeding power to the radiator from the coupler when the electromagnetic waves progress toward the radiator. CONSTITUTION:Electromagnetic waves fed to an antenna device are divided into two and they are connected respectively to feeding waveguides 4-1 and 4-2. The electromagnetic waves from the waveguide 4-1 are fed to a radiator 1a in the power ratio corresponding to the degree of coupling of a coupler 2a and the other is fed to a radiator 1c in the power ratio corresponding to the degree of coupling at a coupler 2c through a waveguide 3a-1, waveguide 5b, and bent waveguide 3b-1, and the rest reaches an aperture II through a bent waveguide 3c-1, waveguide 5d, and bent waveguide 3d-1. Electromagnetic waves from the waveguide 4-2 is fed to radiators 1b, 1d according to the degree of coupling of couplers 2b, 2d. The remaining power reaches an aperture IV through a bent waveguide 3b-2, waveguide 5c, bent waveguides 3c-2, 3d-2, waveguide 5e, and bent waveguide 3e-2. Nonreflection terminating paths are respectively connected to the apertures II and IV. |
