Abstract

In recent years, there has been an increasing demand to improve cellular communication services in several aspects. The aspect that received the most attention is improving the quality of coverage through using smart antennas which consist of array antennas. this paper investigates the main characteristics and design of the three types of array antennas of the base station for better coverage through simulation (MATLAB) which provides field and strength patterns measured in polar and rectangular coordinates for a variety of conditions including broadsides, ordinary End-fire, and increasing directivity End-fire which is typically used in smart antennas. The method of analysis was applied to twenty experiments of process design to each antenna type separately, so sixty results were obtained from the radiation pattern indicating the parameters for each radiation pattern. Moreover, nineteen design experiments were described in this section. It is hoped that the results obtained from this study will help engineers solve coverage problems as well as improve the quality of cellular communication networks.
