A two-dimensional (2-D) discrete dielectric lens antenna is designed to radiate fan-shaped multi-beam patterns for gain stability in beam switching. The target is to minimize adjacent-beam overlapping transition regions and provide sufficient and sim

Multibeam (MB) radiations of antenna arrays rely on effective beamforming networks (BFNs). A 2-D fisheye lens-based BFN (FL-BFN) was developed using a half 2-D lens realizable on metal parallel-plate sandwiched substrates to excite a planar antenna a

An antenna array is developed to radiate angularly distributed multibeams. The proposed antenna utilizes a 2-D Luneburg lens as a beamforming network (LL-BFN) to produce rotationally symmetric excitations. The concept is to replace an equivalent circ
