MULTIMODE ANTENNA Russian patent published in 1994 - IPC

Abstract RU 2022427 C1

FIELD: monopulse antennas. SUBSTANCE: monopulse antenna feed has conical horn connected to round waveguide with waves, types H₁₁, E₀₁ and H₂₁ . Round waveguide has four coupling holes connected to four relatively orthogonal short-circuited sections of rectangular waveguides having length λ_w/4xn, where λ_w is wavelength in waveguide, n = 0 and 1. Pin diode is inserted in sectional area of each rectangular waveguide section at distance λ_w/4(n+1) from coupling hole. EFFECT: simplified design. 2 dwg
