Unlock the Potentials of Large-Element-Spacing Arrays: A Meta-Lens Solution for Grating-Lobe Suppression and Gain Enhancement

Unlock the Potentials of Large-Element-Spacing Arrays: A Meta-Lens Solution for Grating-Lobe Suppression and Gain Enhancement

Large-element-spacing (LES) antenna arrays present an attractive proposition with their cost-effectiveness and simplified structures. However, they often encounter the challenge of high-level grating lobes. This paper proposes a novel meta-lens methodology to effectively address the grating lobe iss...
