Abstract
A wideband high frequency bandpass filter uses a metamaterial transmission line composed of an open-circuit resonator and a short-circuit resonator to realize a bandpass filter at the band of 60 GHz. The bandpass filter has an ultra-wide passband resulting from the coupling of the two resonators in the resonant modes thereof. The ultra wide passband formed by resonance coupling includes a left-handed passband and a right-handed passband. The two passbands jointly provides a passband ranging from 57.4 GHz to 63.6 GHz and having a bandwidth of 6.2 GHz. The stopbands of the bandpass filter are respectively extended downward from 57.4 GHz to the DC current and extended upward from 63.6 GHz to 109.4 GHz. The bandpass filter of the present invention can be applied to wireless transmission at the band of 60 GHz.
