Abstract

The embodiment of the invention discloses a beam forming antenna. The beam forming antenna comprises an antenna array and a feed network, wherein the antenna array comprises M*N antenna oscillators, wherein M and N are greater than or equal to 6 respectively; the feed network comprises a dual-beam feed network and N power dividers capable of dividing one into M, the dual-beam feed network comprises a first beam port, a second beam port and N output ports, the N output ports are connected with the input ports of the N power dividers respectively, and the output ports of the N power dividers arecorrespondingly connected with the N lines of antenna oscillators respectively; when a feed signal input at the first beam port or the second beam port is used for feeding the N lines of antenna oscillators, an arithmetic progression is formed by the phase distribution of the N lines of antenna oscillators by carrying out reversal 180-degree treatment on the feeding of later N / 2 lines of antennaoscillators. By adopting the beam forming antenna, dual narrow beams and the forming antenna with rapid roll-off characteristic can be realized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a beam-forming antenna. Background technique [0002] Beamforming can generate directional beams by adjusting the weighting coefficients of each element in the antenna array, so that specific pattern characteristics can be obtained. Therefore, beamforming technology has great advantages in expanding coverage, improving edge throughput, and interference suppression. When the beamforming antenna is used in crowded scenes such as high-density venues, the beamforming antenna is usually required to have the characteristics of fast beam roll-off and low side lobes, so as to reduce the interference between different sectors. [0003] Existing beamforming antennas usually have a wider lobe width, and the roll-off speed of the lobe width is slower, resulting in greater interference. With the improvement of capacity requirements, it has gradually been unable to meet customer needs,...
