A 5g mobile terminal antenna system and its application

Abstract

The invention provides a 5G mobile terminal antenna system working in the millimeter wave and Sub-6G frequency bands and its application, belonging to the technical field of wireless communication and antennas. The antenna system of the present invention includes a rectangular metal waveguide cavity, a rectangular radiation slot, a stepped radiation slot, and a metal post; and the millimeter-wave antenna and the low-frequency antenna coexist, and are integrated in the substrate and frame of the mobile phone, without the need for a phased array In the case of high gain and large coverage, the win-win situation can be achieved. The substrate-integrated waveguide leaky-wave antenna described in the present invention can work together with the Sub-6G antenna, and the millimeter-wave antenna and the low-frequency antenna are integrated into the mobile phone frame at the same time, saving space. The present invention realizes high coverage of mobile terminals through 12 leaky-wave antennas with different radiation directions, avoids the traditional use of phased array antennas with high cost and complicated structure, does not need beam scanning, and greatly reduces the complexity of software and hardware.
