Abstract

The invention discloses a tight coupling array antenna applied to a 5G communication system. By adoption of an interdigital dipole antenna array plate 10, a grid form resistive frequency selection surface plate 20, the multilayered structure of a grounding plate (GP) 30, and a tight coupling array, the problem that the antenna array is limited in the 5G frequency band impedance bandwidth and the influence on the antenna performance from the grounding plate (GP) 30 in the prior art are solved; a technical effect of small size and large bandwidth is realized; powerful support to the research of the 5G large-scale array antenna is supplied; the relative bandwidth of the antenna provided by the invention can reach 149.1%; and the active standing-wave ratio at the frequency band of 2.8-19.2GHz can satisfy a condition that Active VSWR is less than 3. The tight coupling array antenna can be widely applied to the design field of the 5G antenna.

Description

technical field [0001] The present invention relates to the field of antennas, in particular to a 5G antenna. Background technique [0002] 5G, the fifth-generation mobile phone mobile communication standard, also known as the fifth-generation mobile communication technology, is also an extension after 4G. Mobile communication has experienced the development from 1G analog technology to 4G Long Term Evolution (LTE) technology, and has been used by more than 2 / 3 of the people in the world, becoming an indispensable part of people's daily life. LTE construction is in the ascendant, and 5G mobile communication technology has begun to be widely studied. [0003] IMT (International Mobile Telecommunication)-2020 currently defines large-scale antennas, new multiple access, high-frequency communication, ultra-dense networking, new network architecture, full-duplex, low-latency high-reliability communication, Internet of Things, etc. new technology. Among them, large-scale antenn...
