Abstract: We propose a focusing antenna based on corrugated waveguide scattering at 20 GHz. Surface waves propagating on a low-loss 1-D corrugated waveguide are scattered out of the waveguide to form ...

Abstract: This letter presents an ultrawideband antipodal Vivaldi antenna from 1 GHz to 40 GHz for photonic-assisted reconnaissance. The antenna's performance is enhanced through a systematic ...

TV antennas might seem like a relic of a bygone era, when the number of channels you received could be counted on one hand. But as consumers try to trim their ever-escalating cable and satellite TV ...
