technical field [0001] The invention relates to a millimeter-wave digital multi-beam magnetic dipole array realization device for a mobile terminal, belonging to the technical field of wireless communication. Background technique [0002] Millimeter waves can provide a wide range of available spectrum in future wireless communication systems, which are used to support wide signal bandwidth resources and meet the requirements of high data throughput in communication systems. While mmWave cellular has great potential, electromagnetic waves at mmWave frequencies suffer from high attenuation due to free-space path losses. Fortunately, the shorter millimeter-wave signal wavelength can use antenna arrays in a smaller space to obtain higher antenna gain, and realize the flexibility of millimeter-wave systems through advanced multi-beam or beam scanning technology. [0003] Digital multi-beam technology adopts advanced digital domain beamforming technology. The precoded MIMO commun...

Problems solved by technology

However, the use of a single digital multi-beam array has limited scanning coverage and cannot meet the needs of handheld terminal equipment to cover all-round hemispheres in the entire three-dimensional space.

For this practical problem, the industry has not had a clear solution so far, but with the rapid development of millimeter wave communication systems, the necessity and practical significance of proposing a solution for all-round coverage of terminal equipment signal radiation is self-evident Metaphor
