Abstract

The present invention relates to an array antenna and a wireless communication device. The array antenna comprises a plurality of antenna units arranged at intervals along a transverse direction; at least one surface of each antenna unit is provided with a plurality of radiating oscillators, wherein a plurality of radiating oscillators on the same surface are arranged at intervals along an axial direction; a plurality of radiating oscillators on one surface of one antenna unit and a plurality of radiating oscillators on one surface of another adjacent antenna unit are staggered from each other; and the projection of one radiating oscillator of one antenna unit on one surface of another adjacent antenna unit in a lateral direction does not overlap with the radiating oscillators on the surface. The antenna units are provided with the plurality of radiating oscillators, so that the number of the antenna units is reduced with the same radiating ability realized, and a space occupied by thearray antenna is reduced; and the radiating oscillators of the adjacent antenna units are arranged in a staggered manner, and therefore, a minimum interval required by isolation can be met, an interval between two adjacent antenna units in the transverse direction is reduced, and the development of miniaturization is promoted.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an array antenna and wireless communication equipment. Background technique [0002] At present, MIMO (Multiple-Input Multiple-Output) technology is more and more applied in the field of wireless communication, such as base station antenna or wireless access equipment. MIMO technology can use multiple transmitting antennas and receiving antennas at the transmitting end and receiving end respectively, so that signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving communication quality. Moreover, the use of MIMO technology can also make full use of space resources, and realize multiple transmission and multiple reception through multiple antennas. Without increasing spectrum resources and antenna transmission power, the system channel capacity can be doubled, showing obvious advantages. It is regarded as the...
