Abstract

The invention provides an antenna system and a mobile terminal. The mobile terminal comprises a metal frame. The metal frame comprises two corners which are arranged diagonally, a long frame and a short frame, wherein the long frame and the short frame are connected to the two ends of the corners. The antenna system comprises four SIW horn antenna arrays formed on the metal frame. The circumference side of each corner is provided with two SIW horn antenna arrays which are vertical to each other. One SIW horn antenna array is arranged at one end of the long frame connected to the corner, wherein the end is close to the corner. Another SIW horn antenna array is arranged at one end of the short frame connected to the corner, wherein the end is close to the corner. The SIW horn antenna arrayscomprise a plurality of SIW horns. The positions of the metal frame, which correspond to the SIW horns, are provided with a plurality of through holes which are arranged at intervals. The total covering efficiency of the antenna system and the mobile terminal is good.

Description

【Technical field】 [0001] The present invention relates to the technical field of wireless communication, in particular to an antenna system and a mobile terminal. 【Background technique】 [0002] As 5G is the research and development focus of the global industry, it has become an industry consensus to develop 5G technology and formulate 5G standards. At the 22nd meeting of ITU-RWP5D held in June 2015, the International Telecommunication Union ITU clarified three main application scenarios of 5G: enhanced mobile broadband, large-scale machine communication, and high-reliability and low-latency communication. These three application scenarios correspond to different key indicators. In the enhanced mobile bandwidth scenario, the user peak speed is 20Gbps, and the minimum user experience speed is 100Mbps. The unique high carrier frequency and large bandwidth characteristics of millimeter wave are the main means to achieve 5G ultra-high data transmission rate. [0003] The abund...
