Description
technical field [0001] The present invention relates to 4G wireless communication technology, in particular to a terminal MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) antenna device and antenna signal transmission method. Background technique [0002] For 4G wireless communication technology, LTE technology can provide faster speed and better multimedia services. At the same time, people have higher and higher requirements on the efficiency and portability of wireless terminal equipment, so the antenna technology of various communication terminals has also made great progress. Since the physical size of the antenna radiator is related to the resonant frequency, the functions of the current wireless terminal are diversified, and the thinning of the terminal directly leads to a smaller and smaller limited environment for the antenna. The integration, miniaturization, and broadband of the antenna are antenna devices. inevitable development trend. [0...
