CORNER ANTENNA Russian patent published in 2002 - IPC

FIELD: radio engineering; antenna systems for very-high-frequency communication systems including cellular ones. SUBSTANCE: antenna has corner reflector 16 with aperture angle ϕ formed by conducting plates 10, 12 that function as main mirrors and antenna feed 18 disposed inside corner reflector. Additional conducting plates 26, 28 are introduced in corner reflector to function as additional mirrors. Plates 26, 28 are tilted through angles α and β to aperture of corner reflector, their edges are parallel to those of conducting plates 10, 12 of main mirrors and to edge 14 of corner reflector. Values of angles ϕ, α and β are chosen from conditions α, β, ϕ<π; α+β+ϕ>2π. EFFECT: provision for developing corner antenna with sector-shaped directivity pattern in azimuth plane. 11 cl, 4 dwg
