Analysis of Application Technology of Railway 5G-R Base Station Antennas
This study provides an overview of the structure and basic technical parameters of base station antennas.Based on the specifications of railway 5G-R base stations,the technical characteristics of three types of antennas,i.e.panel antennas,Luneburg lens antennas,and innovative integrated antennas were investigated.Additionally,the advantages and disadvantages of the three types of antennas were compared and analyzed to provide recommendations for the selection of base station antennas of the 5G-R system.In line with the specific operational mode of railway 5G-R base stations,the connection method between antennas and RRUs was proposed,and the types of antenna interfaces were analyzed and compared.Furthermore,suggestions were offered for the configuration of the antenna information management module to meet the intelligent operation and maintenance requirements of the 5G-R system.The findings can serve as a reference for the selection and operation of railway 5G-R base station antennas.
