Review on filtering antenna technology for 5G mobile system

Abstract

Abstract In recent years, people’s increased demand for wireless communication technology fuels the development of 5G communication technology growth. Electronic equipment in the current wireless communication system is developing in the direction of low power consumption, multi-function, miniaturization, and integration, which also puts higher technical standards for RF front-end. In recent years, the wireless communication industry is building lighter, thinner, and smaller products with multifunction. The integration of filter and antenna is one of the important ways for the miniaturization of electronic systems. The antenna and filter are integrated to form a filtering antenna, which can effectively reduce the size and weight of the RF front end while realizing the function of radiation and filtering. This paper first introduces the research background and significance of this topic according to the background of mobile communication technology, and the main challenges faced by 5G communication. Then, the working principle of filtering antenna and multiple-input multiple-output technology (MIMO) are introduced, and finally the development and research status of 5G filtering antenna are summarized, and some relevant personal views are put forward.
