Problems solved by technology

However, since the current form of SIW power divider is mainly single-layer "T-shaped section" and "Y-shaped section", which occupy a huge plane space, it is not convenient for the integration of antennas, especially linear array antennas.

Abstract

The invention discloses a compact 5G dual-band millimeter wave linear array antenna based on SIW feed, which is applied to 5G millimeter wave communication and comprises a multi-layer SIW power divider and a dipole slot combined dual-band antenna. In the power division network, a transverse seam is formed in a metal layer of the SIW and used for cutting surface current, so that electromagnetic wave energy conducted internally can be coupled to the upper layer through the seam. The basic structure of the power division network is similar to that of a T-shaped power divider, and the eight antenna units are fed in a three-stage cascade mode. A low-frequency dipole mode and high-frequency slot mode composite dual-frequency antenna is designed as an antenna unit by comprehensively considering loss and matching. Miniaturization and compactness of the linear array antenna structure are realized.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a compact 5G dual-band millimeter wave linear array antenna based on SIW feeding. Background technique [0002] In 5G mobile communications, the spectrum allocation of millimeter wave multi-bands leads to a substantial increase in the types and quantities of base station antennas. In order to realize the full utilization of 5G spectrum resources and space resources, the flexibility of frequency band selection is improved, and a compact 5G dual-band millimeter wave array is realized. Antennas are very important for 5G mobile communications. [0003] The substrate integrated waveguide (SIW) structure can easily integrate active devices and passive devices on a dielectric board. Since there is no transmission line as a feed structure, energy loss and mutual coupling of transmission lines are greatly reduced. Using SIW as the feed structure can reduce the antenna performance impact...
