【摘要】 本文提出了一种基于拓扑优化的宽带双极化偶极子天线。利用偶极子的对称特性,对偶极子的一个臂进行碎片化拓扑优化,从而使得该偶极子的阻抗带宽能够被大大拓宽。基于拓扑优化的偶极子天线能够在3.18～5.55 GHz实现VSWR<2 (相对带宽为54.3%)。相比拓扑优化的偶极子天线,阻抗带宽提高了29.1%。更多还原

【Abstract】 This paper proposes a broadband dual-polarized dipole antenna based on topology optimization.By exploiting the symmetry of the dipole structure, one arm of the dipole is optimized through fragmented topology optimization,which significantly broadens its impedance bandwidth.The topology-optimized dipole antenna achieves a voltage standing wave ratio(VSWR) below 2 across 3.18～5.55 GHz,corresponding to a fractional bandwidth of54.3%.Compared to the conventional dipole antenna,the impedance bandwidth is improved by 29.1 %.更多还原
