There is an urgent need for high-capacity connection with high data transfer rate in densely populated areas due to the rapid growth of mobile communication technologies and the explosion of data traffic. Multi beam antennas have generated a lot of research interest and have been extensively explored for base station applications due to their ability to boost communication capacity and sustain a high data transfer rate. Multi-beam antennas based on Butler matrices (MABBMs) are also appropriate for base station applications because to their advantages of high gain, simple design, and low profile. This paper's goal is to give a summary of the current MABBMs. The presentation of MABBMs includes its specifications, operating principles, design methodology, and implementation. In the final section, the difficulty of MABBMs for 3G/LTE/5G/B5G base station applications is discussed. The paper is divided into six sections, in the first section an introduction, in the second section base station application standards are presented, the design strategy and operating principles of MABBMs in the third section, and the latest developments in MABBM research for mobile communication systems are addressed in the fourth section, and challenges are presented in fifth Section, and conclusions are presented in the sixth Section.
