Unlock the Potentials of Large-Element-Spacing Antenna Arrays

The event titled "Unlock the Potentials of Large-Element-Spacing Antenna Arrays" is included in the series of DET Talk and will be on 12 July 2024 at 2,00 pm with special guest the professor Yuehe Ge, a renowned expert in antenna technology at the College of Physics and Information Engineering of Fuzhou University, in China.

Antenna arrays with large-element-spacing (LES) offer advantages such as lower cost and less structural complexity. However, they typically suffer from high-level grating lobes, limiting their applications. Therefore, grating-lobe suppression technology in low-profile, high-gain planar antenna arrays has long been an interesting focus for antenna researchers.
In this talk, I will introduce a novel method to eliminate or reduce grating lobes in sparse, thinned, and uniformly large-element-spacing (LES) antenna arrays. Additionally, The radiation performance of the LES array, focusing on achieving high gain, high aperture efficiency, low sidelobes, and effective beam scanning, has been investigated. The results are promising and will be presented in detail. While our investigation is based on uniformly spaced LES antenna arrays, the conclusions drawn can also be applied to non-uniform, sparse, or thinned arrays.
