This paper describes the design of a planar antenna array system with pattern reconfiguration in the azimuthal plane. The antenna array system is designed based on four antenna units where each unit is composed of two printed Yagi-Uda elements that radiate in directional beams over a dedicated sector. thus ensuring maximum isolation with neighboring units. The various units are fed on... https://herbsdailyes.shop/product-category/pill-crushers-and-cutters/
