TL;DR: In this article, a dual polarized feed by which two linearly polarized waves can be reliably separated over high frequency coaxial cables is proposed. But the two waves are conducted separately over high-frequency coaxial cable, one extending axially and the other radially into the polarizer.
Abstract: The present invention relates to a dual polarized feed by which two linearly polarized waves can be reliably separated. The two waves are conducted separately over high frequency coaxial cables, one of which extends axially and the other radially into the polarizer. Rotation of the planes of polarization is thus unnecessary and the two cables have a minimum influence on the illumination (irradiation) of the reflector.

TL;DR: In this paper, a dual frequency band horn-type antenna feed is described which has primary application to optimally illuminate a parabolic cylindrical reflector operating simultaneously at high power in both of the two bands.
Abstract: A dual frequency band horn-type antenna feed is described which has primary application to optimally illuminate a parabolic cylindrical reflector operating simultaneously at high power in both of the two bands. The principle of the invention is applicable to any two frequency bands regardless of their frequency separation including coincidence as a limiting case. The basic requirement of such a feed is that it must be as directive as possible within constraint of the feed aperture size in the plane of the cylinder axis because the cylindrical reflector does not collimate the beam in this plane and it must be relatively nondirective in the plane of the parabola for efficient illumination of the reflector. This requirement requires the phase front in the directive plane to be controlled within a small fraction of a wavelength at both frequencies.

TL;DR: In this paper, a horn lens antenna designed for the generation of OAM-carrying radio waves is presented, where the conventional horn antenna is integrated with a single-layer perforated planar dielectric lens by covering its aperture.
Abstract: A horn lens antenna designed for the generation of OAM-carrying radio waves is presented. The conventional horn antenna is integrated with a single-layer perforated planar dielectric lens by covering its aperture. Through varying the diameter of holes, an azimuthal variation of the permittivity is obtained and the corresponding azimuthal phase delay creates a vortex, thus an OAM wave is generated. The lens antenna works in the millimeter frequency band, and can be used to generate the OAM states of l =+1 or −1.

TL;DR: In this paper, an antenna for directional electronic communication, a directional communication system, a method of conducting directional communications, a combat identification system and a method for identifying friendly forces is presented.
Abstract: An antenna for directional electronic communication, a directional communication system, a method of conducting directional communication, a combat identification system and a method of identifying friendly forces. In one embodiment, the antenna includes: (1) a conductive shield having an opening at an end thereof and a radio frequency absorptive material located on an inner surface thereof, (2) a Luneberg lens located within the conductive shield and (3) a feed horn located proximate a portion of the Luneberg lens that is distal from the opening.
