The embodiments of the present invention provide a millimeter-wave dual-polarized slot antenna array. The millimeter-wave dual-polarized slot antenna array comprises an antenna unit layer, a first feed network layer and a second feed network layer which are stacked sequentially; the antenna unit layer comprises a first pre-set number of first slot antenna elements, wherein the first slot antenna element is a cross-shaped slot antenna element of which the four narrow edges are semicircular; the second feed network layer uniformly couples generated second electromagnetic waves to the first feed network layer in an equal-phase manner through the third slot antenna element; and the first feed network layer is used for generating first electromagnetic waves perpendicular to the direction of the second electromagnetic waves, uniformly coupling dual-polarized electromagnetic waves to the antenna unit layer in an equal-phase manner through the second slot antenna element and radiating the dual-polarized electromagnetic waves to a free space through the first slot antenna element. With the millimeter-wave dual-polarized slot antenna array provided by the embodiments of the present invention adopted, the working bandwidth of the antenna array is improved.
Description
technical field [0001] The invention relates to the technical field of antennas for wireless communication terminals, in particular to a millimeter-wave dual-polarization slot antenna array. Background technique [0002] With the rapid development of multimedia technology and network technology, the demand for bandwidth of wireless communication is also increasing rapidly. Traditional low-frequency wireless spectrum resources are also gradually becoming saturated. Although the use of high-order modulation or multiple access technology can expand the capacity of the communication system and improve spectrum utilization, the improvement in bandwidth is very limited. In order to further meet the bandwidth requirements of communication terminals and realize high-speed broadband wireless communication, it is necessary to develop new wireless spectrum resources. [0003] In recent years, research on planar antenna arrays operating in the millimeter wave band has attracted more an...
