Abstract
An antenna, suitable for battlefield identification use, employs a multifunctional design. A closed-end coaxial line structure with center conductor has slanted slot radiators provided in its outer conductor. The slot radiators excite a pattern between upper and lower disks of a radial waveguide radiator configuration so that horizontal and vertical components reach the disk circumference with a 90 degree phase differential to provide an omnidirectional antenna pattern of circular polarization. Antennas and methods are described.
