Abstract: A wide-bandwidth antenna with antenna pattern control includes a radiator and a feed. The radiator includes two or more volumetric radiating elements. The feed includes two or more feed units, the feed units configured to provide wave signals to the volumetric radiating elements. The feed units provide an independent signal for each radiating element. The wave signals can be fed out of phase to each other. Depending on the dielectric filler inside the volume of the antenna and the phase shift between feeds, the pattern can be modified electronically leading to pattern control. The radiating elements are spaced at a distance at least one order of magnitude smaller than half of an operational wavelength of the antenna. At least one electrically conductive element of the antenna is capable of conducting a current that generates a magnetic field. The magnetic field lowers the total reactance of the antenna, thereby resulting in enhanced performance of the antenna in terms of bandwidth, gain, and pattern control.

Abstract: A wide-bandwidth antenna (e.g., a rib-dipole antenna) includes a first pole formed by a first conductive member and/or a second pole formed by a second conductive member. The antenna also includes an antenna feed between the first conductive member and the second conductive member. The antenna also includes at least one electrically conductive element including a surface. A portion of the surface is electrically connected to, and extends from, the first conductive member or the second conductive member. The at least one electrically conductive element is capable of conducting a current that generates a magnetic field. The magnetic field lowers a total reactance of the antenna, thereby resulting in enhanced performance of the antenna and more efficient use of volume.
