Wideband Multi-Mode Leaky-Wave Feed for Scanning Lens Phased Array at Submillimeter Wavelengths

In this article, we propose a hybrid electromechanical scanning lens antenna array architecture suitable for the steering of highly directive beams at submillimeter wavelengths with field-of-views (FoV) of ±25°. The concept relies on combining electronic phase shifting of a sparse array with a mechanical translation of a lens array. The use...
