摘 要: | 研究了微带分形阵列天线,并设计出二阶正方形迭代微带分形阵列天线与一阶Koch微带分形阵列天线,借助电磁仿真软件HFSS 10.0进行仿真优化,使得这两款微带分形阵列天线分别适用于4.20 GHz/5.80 GHz和4.75 GHz/5.80 GHz频段。经研究可知:此两款阵列天线分别与各自的单元天线相比,增益性明显提高,交叉极化隔离度和各端口隔离度都大于15 dB,且均实现圆极化特性。此两款微带分形阵列天线满足了多输入多输出(multiple input multiple output,MIMO)系统天线小型化、多频段、圆极化、合理的增益、低相关的设计要求,为MIMO系统设计阵列天线提供了一定的借鉴。 |

Abstract: | Second-order square iteration microstrip fractal array antenna and first order Koch microstrip fractal array antenna are designed in this paper. Using HFSS 10.0 to simulate and optimize antenna models, so that the two microstrip fractal array antennae are suitable for 4.20 GHz/5.80 GHz bands and 4.75 GHz/5.80 GHz bands, respectively. It can be seen that the two array antennae’s gain is significantly improved, cross-polarization isolation and the port isolation are greater than 15 dB, and both achieve circular polarization. The two microstrip fractal array antennae meet the small size, multi-band, circularly polarized, reasonable gain, and low-related design requirements for the multiple input multiple output (MIMO) system to provide a certain reference value. |
