With the rapid development of wireless communication technologies,electromagnetic compatibility issues between devices in the process of communication transmission have become more and more serious.The base station is the core device of wireless communication for information transmission.With the 4G communication technology,it is developed in the direction of large capacity,multi-function and ultra-broadband.Therefore,the requirements for communication transmission to the base station are also getting higher and higher.As an important part of the base station,the antenna need to consider the electromagnetic compatibility problem between the antenna and the base station.This article mainly studies the electromagnetic interference transmitted from the base station and the antenna.First,the influence of interference on the wireless communication is discussed through the measurement of the spatial base station.Then,the specific reason is analyzed according to the interference received by the base station,and the optimal antenna is selected.Analyze the electromagnetic compatibility of the antenna based on the simulation results of the antenna,and finally perform a comprehensive analysis of the electromagnetic compatibility of the base station and the antenna.This paper builds a base station measurement platform for wireless communication,based on TDD-LTE technology,conducts on-site measurement of the base station,and records the type of interference in the base station for communication.The data measured by the equipment and theoretical calculations are analyzed to eliminate the influence of interference in the base-station.Then select the matching antenna to transmit,analyze the structural design features and functions of the conical antenna,use the Ansoft HFSS software to simulate the antenna,and analyze the electromagnetic compatibility problem of the antenna.Finally,considering the antenna center frequency of 1895 MHz,2330MHz and 2580 MHz,the matching performance of the antenna and the-base station.As an important branch of electromagnetic compatibility,electromagnetic interference(EMI)matches the optimal antenna for communication transmission by analyzing the interference problems in the base station.Therefore,it becomes extremely important to analyze the electromagnetic compatibility problem between the antenna and the base station.In order to create a good space transmission environment,reduce the mutual interference between devices and ensure the quality of wireless communication transmission.This provides theoretical and technical evidence for the development of wireless communications.
