| titleOfInvention | Broadband omnidirectional microwave antenna with decreased sky radiation and with a simple means of elevation-plane pattern control |
| abstract | An omnidirectional microwave antenna comprises a paraboloidal reflector disposed above the ground and facing downwardly with a substantially horizontal aperture and a substantially vertical axis. A vertically oriented feed horn is located below the paraboloidal reflector on the axis of the paraboloidal reflector and has a phase center located near the focal point of the paraboloidal reflector. A conical reflector extends downwardly away from the periphery of the feed horn for reflecting radiation received vertically from the paraboloidal reflector in a horizontal direction away from the conical reflector, and for reflecting horizontally received radiation vertically to the paraboloidal reflector. A radome extends downwardly from the outer periphery of the paraboloidal reflector and includes an absorber material for absorbing radiation propagated laterally from the feed horn and the conical reflector above the aperture of the feed horn. |
