Abstract
An X, Ku, and K-band omni-directional antenna with dielectric loading is disclosed. It comprises a conductor with a loading dielectric resonator and a ground plane. Broad frequency coverage from 7.5 to 26 GHz includes uniform azimuthal coverage from +10 to +70 degrees. The antenna can be used generally in microwave communications including Digital Radio Frequency Tags (DRaFTs) communicating with airborne and satellite platforms.
