3D printed optimized phased array with volumetric emitters
2023 Days on Diffraction (DD)(2023)
摘要
This paper presents a phased array antenna with volumetric elliptical elementary radiators optimized with genetic and swarming algorithms. The emitters themselves were manufactured using the SLA method. The presented geometry is compact (the aperture is only 2 wavelengths) and has a high gain about 11–14 dBi in a wide operating band (2.5–4.5 GHz). To describe inner modal structure and understand far field formation properties of this array, multipole decomposition is used.
