Abstract

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.
