Method and apparatus for a high-performance compact volumetric antenna

摘要

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.

1. A wide-bandwidth antenna comprising:
a first pole formed by a first conductive member; a second pole formed by a second conductive member; a first antenna feed between the first conductive member and the second conductive member; a third pole formed by a third conductive member; a fourth pole formed by a fourth conductive member; a second antenna feed between the third conductive member and the fourth conductive member; at least one electrically conductive element including a surface having a portion that is electrically connected to, and extends from, at least one of the first conductive member, the second conductive member, the third conductive member or the fourth conductive member, the at least one electrically conductive element capable of conducting a current that generates a magnetic field that lowers a total reactance of the antenna, wherein when the first antenna feed and the second antenna feed are fed 180 degrees out of phase relative to one another, the antenna pattern of the wide bandwidth antenna is a toroid with an axis of rotation along an axis perpendicular to both a longitudinal axis and an axis defined by the first antenna feed and the second antenna feed; wherein the first pole, the second pole, and the first antenna feed define a first half cylinder volume; the third pole, the fourth pole, and the second antenna feed define a second half cylinder volume; the first half cylinder volume and the second half cylinder volume sharing the longitudinal axis.
