A system may include a base portion, first and second support members coupled to the base portion, a first plurality of tapered slot antenna (TSA) pairs coupled to the first support member, and a second plurality of TSA pairs coupled to the second support member. The first plurality TSA pairs are oriented at a non-zero angle about a first axis of the first support member and are oriented at a non-zero angle about a second axis of the first support member, with the second axis being perpendicular to the first axis. The second plurality TSA pairs are oriented at a non-zero angle about a first axis of the second support member and are oriented at a non-zero angle about a second axis of the second support member, with the second axis being perpendicular to the first axis.

Tapered slot antenna hemispherical array

An ultra-wideband antenna is provided. The antenna includes a cone shaped ground element and a radiating element. The cone shaped ground element has a first vertex region and an aperture formed through the first vertex region. The cone shaped ground element is configured to form an electrical ground. The radiating element includes a cone shaped radiator and a spherical shaped radiator. The cone shaped radiator has a second vertex region that is electrically connectable to a feed element mounted through the aperture of the cone shaped ground element. The spherical shaped radiator is mounted to the cone shaped radiator opposite the second vertex region.
