Abstract
The present disclosure provides an antenna array, a tapered slot antenna element, and an antenna panel. The antenna array includes a plurality of antenna panels each comprising, respectively: a substantially planar base section, and at least one tapered slot antenna element projecting in a direction away from an extent of the base section along the direction. The base sections of the plurality of antenna panels are disposed in parallel with each other. The tapered slot antenna elements of the plurality of antenna panels provide a plurality of polarizations.

An antenna array comprising:
- a plurality of antenna panels each comprising, respectively:
- a substantially planar base section, wherein the base sections of the plurality of antenna panels are disposed in parallel with each other;
- and
- at least one tapered slot antenna element projecting in a direction away from an extent of the base section along the direction, wherein the tapered slot antenna elements of the plurality of antenna panels provide a plurality of polarizations.
A tapered slot antenna element comprising:
- a base section disposed in a first plane;
- two radiating fins coupled with, and projecting upwardly from, the base section and disposed in a different second plane;
- and
- a twist section disposed between the base section and the two radiating fins, wherein a slot line extends from between the two radiating fins, through the twist section along a contour thereof, toward the base section.
An antenna panel comprising:
- a substantially planar base section;
- a first set of tapered slot antenna elements coupled with the base section, and projecting in a direction away from an extent of the base section along the direction, the antenna elements of the first set having a first orientation relative to the plane of the base section;
- and
- a second set of tapered slot antenna elements coupled with the base section, and projecting in a direction away from an extent of the base section along the direction, the antenna elements of the second set having a different second orientation relative to the plane of the base section.
