"Here, we report that microwave toroidal pulses can be launched by a transient finite-aperture broadband horn antenna emitter, as an electromagnetic counterpart of 'air vortex cannon'," an ...

We’ve seen our share of 3D printed antennas before, but none as well documented and professionally tested as [Glenn]’s 3D printed and metalized horn antennas. It certainly helps that [Glenn ...

the TanDEM-X-specific synthetic aperture radar instrument features provide a scheme for exchanging synchronisation information through a dedicated link. This comprises a set of six horn antennas, ...

The Horn Antenna was the instrument used by radio astronomers Arno Penzias and Robert Wilson that detected a background noise, later discovered to be caused by cosmic microwave background radiation.
