ABSTRACT:
An X-band, crossed dipole turnstile antenna configured to be omni-directional with horizontal polarization is disclosed. It comprises a set of two dipole antennas aligned at right angles to each other attached to a common 50 ohm coaxial feedpoint and fed 90 degrees out-of-phase. The antenna pattern is nearly omnidirectional in the horizontal plane. The antenna can be used generally in microwave communications including Digital Radio Frequency Tags (DRaFTs) communicating with airborne and satellite platforms.
