      abstract = {This book is designed for both the scientific audience,  research and development engineers and the university  students. The fundamentals of radio frequency antenna beam  forming is explained in this book. The principles of beam  focusing and beam steering in near field and far field are  visualized with 2D and 3D simulations and compared with  measurement results. Besides linear and planar antenna  arrays, also conformal arrays, i.e. concave and convex  antenna arrays, suitable for certain applications, are  investigated and presented. Also related applications of  radio frequency beam forming like open loop and closed loop  large scale antenna arrays or massive MIMO, which is one of  the break-through technologies for 5G and future 6G and  involves an extremely large number of antenna elements for  the multi-user beam forming, as well as thinned antenna  arrays with electrically large distances between the  antenna elements are discussed. Target Group: Students of  electrical engineering and information technology RF  engineers in research and development.},
