摘　　要：This paper presents a compact triple-band bandpass filter based on metamaterials. The miniaturization is realized by the principle of phase compensation of metamaterial. Compared with the conventional half-wavelength filter, the metamaterial filter has a small size of 10 mm×10 mm. The triple-band bandpass filter performance has been validated by the electromagnetic simulation software of high frequency structure simulator(HFSS). The results illustrate that the filter is designed with center frequencies of 2.4 GHz, 5.1 GHz and 8.8 GHz, bandwidths of about 7.9%(2.31—2.50 GHz), 7.8%(5.0—5.4 GHz) and 7.4%(8.50—9.15 GHz), respectively, and it shows good band pass characteristics.This paper presents a compact triple-band bandpass filter based on metamaterials.
