Review paper


In this paper, a multiple fan-beam antenna array is proposed for massive multiple-input multipleoutput (MIMO) applications. The proposed array is based on vertical spatial filtering to reduce radio frequency complexity in a massive MIMO system. A microstrip line feeding network is utilized to achieve a specific phase distribution for multiple fan beams. A 64-element antenna array is designed and fabricated to validate the design strategy. The proposed antenna array uses 16 ports to excite 64 antenna elements, which is more cost effective than traditional massive MIMO systems. The measured results demonstrate that the proposed antenna array can achieve two fan beams at 7 in the vertical dimension, and the measured gain of every port exceeds 10 dBi at 2.6 GHz.
