This study proposes a patch antenna design with a narrow angle of four beams to be
employed in four remote areas. The antenna is designed to radiate four beams in the 5G …

This book describes both known and new results. In the sections devoted to the use of
integral equations for the current in a linear metal radiator, the focus is on Leontovich's …

The goal of the proposed research is to construct the Phase controlled directed antenna
using low-loss dielectric and high relative permittivity material for the substrate. In this paper …
