Spherical-Lens Antennas For Millimeter Wave Radars
1 Spherical-Lens Antennas For Millimeter Wave Radars Bernhard Schoenlinner, Xidong Wu, George V. Eleftheriades and Gabriel M. Rebeiz Abstract-- A low-cost 77 GHz spherical lens antenna has been developed for mobile applications. The antenna system consists of a 5 cm spherical Teflon lens which is fed by an endfire tapered slot antenna on a 127 µm-thick DuroidTM substrate. The measured patterns re
