A micro bandpass filter comprises a substrate, a first signal transmission member, a second signal transmission member and a resonator structure. The resonator structure includes a plurality of microstrip lines. The present invention realizes the function of a bandpass filter in a smaller area via curving the first signal transmission member, the second signal transmission member and the resonator structure.

Micro bandpass filter

A wideband high frequency bandpass filter is disclosed, which includes an open-circuit resonator structure and a short-circuit resonator structure. The open-circuit resonator has a signal transmission strip line and a T-shaped strip line. Both ends of the signal transmission strip line are bent toward to opposite ends of the T-shaped strip line respectively, so as to form gaps in the open-circuit resonator. The open-circuit resonator structure and the short-circuit resonator structure are coupled under the resonant mode, thereby achieving a bandpass filtering at 60 GHz.
