Abstract: A microwave antenna for use in a sectorized cellular communication system comprises a wide-flare pyramidal horn having two pairs of opposed flared side walls. At least one of the two pairs of opposed walls has corrugated interior surfaces. The length of the horn and the flare angle of the walls having the corrugated interior surfaces are selected to produce a ratio &Dgr;e/&lgr; greater than 1.5, where &Dgr;e/&lgr;=[a/(2/&lgr;)] tan (&agr;e/2) is the spherical-wave error of said horn, &lgr; is the free space wavelength of the microwave signals to be transmitted by said antenna, &agr; is the horn's aperture width, and &agr;e the half-angle of the horn in the horizontal plane.

Abstract: A hog-horn antenna for producing two orthogonally polarized signals. The elevation plane pattern of each signal can be made to have virtually any shape, but is typically of a substantially cosecant-squared shape. In providing for the dual-polarization capability, the hog-horn antenna is designed to produce substantially equal gains for orthogonal polarizations, either simultaneously or separately. Two techniques to substantially equate the elevation plane radiation patterns of the two polarizations include corrugating or absorber-lining the surfaces of portions of the hog-horn antenna. Azimuthal pattern control may be achieved by corrugated/absorber lined flanges.
