提出了一种基于分形天线-滤波器-天线（AFA）阵列的小型化带通频率选择表面（FSS）。基于AFA的频率选择器具有上级的频率选择性，并且比传统的频率选择器具有更低的轮廓。然而，它们通常占据相当大的单元尺寸。在这封信中，分形几何形状被用来减少基于AFA的FSS的单元格。分析了Minkowski岛形发射/接收贴片和分形十字形耦合孔径的迭代阶数和迭代因子。制作了一个工作在C波段的FSS样机，并利用波导测量装置进行了测试，测试结果与模拟结果吻合良好。
A novel type of miniature bandpass frequency selective surface (FSS) based on fractal antenna-filter-antenna (AFA) array is proposed. The AFA-based FSSs exhibit superior frequency selectivity and have lower profile than conventional FSSs. However, they commonly occupy considerably large unit sizes. Fractal geometries are utilized in this letter to reduce the unit cell of AFA-based FSSs. The iteration order and iteration factors of the utilized fractals including Minkowski island-shaped transmit/receive patches and fractal cross-shaped coupling aperture are analyzed. A prototype of the proposed FSS operated at C-band is fabricated and tested using waveguide measurement setup, and good agreement is obtained between measured and simulated results.
