Title: Antenna with extended aperture (its variants)
Inventor: SERGEEV VLADIMIR N
IPC: H01Q19/12
Filed: 1992-10-30
Granted: 1996-08-20
Abstract: FIELD: SHF equipment. SUBSTANCE: the antenna has a reflector enclosed between two parallel conducting plates, and a feed in the form of an open end of waveguide. The feed is positioned in the center of the reflector on the external side. Placed between the two conducting plates, in parallel with them, is the third conducting plate separating the reflector and feed in two. A phase-shifting element is placed in the waveguide of one of the halves of the feed. In the first variant one of the reflector halves is made of dielectric. If the reflector is a parabolic one with the axial dimension equal to a half of the focal length, the antenna axial dimension decreases by two times. According to the second variant, one of the reflector halves is shifted in the direction of the antenna radiating aperture by a quarter of the wavelength, which makes it possible to reduce dissipations caused by the dielectric used in the reflector half according to the first variant. In a parabolic reflector the reflector axial dimension is selected to be equal to a half of the focal length for the half that is most distant from the radiating aperture. EFFECT: enhanced efficiency. 4 cl, 3 dwg
