Özet:

 

A multibeam array antenna employing a Butler matrix is a promising solution for fifth generation  5G  base  stations. Due to inaccurate phase differences between output ports in the Butler matrix, the radiation characteristics  could show incorrect main beam directions. In addition, the literature has also reported the issue of high amplitude  imbalance in the Butler matrix. This paper presents a single-layer multibeam array antenna fed by an 8×8 Butler  matrix operating at 28 GHz for 5G base station applications' a more cost-effective solution for large-scale production.  The Butler matrix consists of twelve quadrature hybrids, sixteen crossovers, and eight phase shifters. This circuit was  integrated with eight antenna elements at the output ports of the Butler matrix. The proposed multibeam array antenna  was fabricated using a low dielectric constant and a low loss tangent substrate. The dimensions of the multibeam array  antenna were 88×106×0.254~mm33^3 . The Butler matrix achieved low insertion losses and low phase error with average  values of 2.5 dB and less than ±10  ? at 28 GHz, respectively. The measured return losses were less than ±10∘±10∘\pm10^\circ dB at  28 GHz. The measured radiation patterns were obtained and eight main beams were pointed at ±6  ±18∘±18∘\pm18^\circ   ±30∘±30∘\pm30^\circ   and  ±44∘±44∘\pm44^\circ  with measured gains between 9 dBi and 14 dBi.
