Massive MIMO technology is one of the key technologies of the 6G
communication system and the basis of high-speed transmission in the wireless
communication network. At the same time, massive MIMO puts forward new
requirements for antenna devices in the communication system, such as active
integration, miniaturization, broadband, etc. This chapter first reviews the development
process and the latest progress of antenna technology in wireless communication. The
requirement of a 6G communication network for the base station antenna and the
terminal antenna is emphasized. The theoretical basis of massive MIMO technology in
the 6G communication system is described in detail, and RIS technology which is
closely related to massive MIMO, is introduced. The technical characteristics and
development trends of massive MIMO antennas are discussed in detail, including
antenna design and synthesis, feed network, and antenna selection technology. Finally,
combined with the development of current antenna measurement and calibration
technology, the measurement engineering technology closely related to the antenna
feeder industry in 6G communication is introduced.
