title = "W-Band Broadband All-Metal Luneburg Lens Antenna Integrating Dual-Mode Transducers for Wide-Angle Tracking Applications",
abstract = "In this article, a broadband full-metal Luneburg lens antenna is proposed, achieving multiple sum-difference beams within a wide-angle Azimuth coverage. The metallic parallel-plate Luneburg lens employs glide-symmetric pins in parallel plate with gradient heights to realize required refractive index distribution. Furthermore, multiple TE10/TE20 dual-mode transducers based on groove gap waveguide are integrated with the lens as the feeds, providing odd and even mode excitation simultaneously. The proposed monopulse Luneburg lens antenna achieves seven pairs of sum- and-difference beams for H-plane within a ±60° scanning range. The antenna impedance bandwidth covers the entire W-band (75-110 GHz, 37.8\%). The sum beam gain ranges 17.9-20.5 dBi, with an maximum aperture efficiency of 88\%.",
