提出了一种新型的小型化滤波天线。利用高Q扇形折叠波导谐振器设计了四极点准椭圆带通原型滤波器，获得了较低的插入损耗和回波损耗。为了有效利用空间，将折叠天线与滤波器集成在一起。因此，滤波天线不仅具有非常紧凑的尺寸，而且在通带内具有平坦的高增益。为了进行实验演示，由于内部结构复杂，采用了金属3D打印技术。最后的测量显示出有趣的和有前途的结果，这在本文中。
This paper presents a novel compact filtering antenna. The high-Q Fan-Shaped Folded Waveguide resonator is utilized to design four-pole quasi elliptic bandpass prototype filter which obtained lower insertion and return loss. Then for utilizing space effectively, folded antenna is integrated with the filter. As a result, the filtering antenna not only owns very compact size but also enjoys flat high gain in the passband. For experiments demonstration, metal 3-D printing techniques was adopted due to the complex inside structures. The final measurements have shown interesting and promising results, which are presented in this paper.
