This paper presents the modeling and design of a frequency agile antenna using an anisotropic artificial dielectric layer (AADL) for multi-band phased array radar applications. The proposed AADL material is placed underneath the patch radiator and is designed using periodically arranged metallic cylinders in which varying height. diameter. and the distance used between them allows the... https://pipingrockers.shop/product-category/lithium-orotate/
