Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to an eight-unit MIMO handheld terminal antenna in the 5G frequency band. Background technique [0002] With the rapid development of wireless communication technology, people have higher and higher requirements for data transmission speed. The fifth generation (5G) wireless communication system is planned to be commercialized in 2020, and the core technology of 5G mobile communication is fully developed. [0003] The frequency band used by the 5G wireless communication system is the millimeter wave band below 6GHz and above 6GHz, and 3.5GHz and 28GHz are the main 5G frequency bands for millimeter wave below 6GHz and above 6GHz. [0004] The traditional antenna has the disadvantage of low communication efficiency due to the low transmission rate, which can no longer meet the requirements of the 5G era. [0005] MIMO (Multiple Input Output) antenna technology improves...
