摘要：

A 45.2 similar to 67.2 GHz substrate integrated waveguide (SIW) bandpass filter (BPF), which is fabricated by using Integrated Passive Device process (IPD), is proposed in this paper. The complementary split-ring resonator (CSRR) etched on the SIW and the coplanar to waveguide conversion structure arc adopted to realize the performance of low loss, wide bandwidth and miniaturization. The transmission zeros, which is generated by using the CSRRs etched on the SIW, are located to the right of the passband and are flexible adjustability. The measurement results show that the operating frequency of the presented SIW BPF is range from 45.2 GHz to 67.2 GHz and the return loss of the filter is better than -25dB. This proposed 51W BPF has a minimum insertion loss of -1.44dB at 54.90GHz and a fractional bandwidth of-39"/o. The filter has the advantages of small size, low loss, large power capacity and wide passband, and so on. This BPF presented in this paper is suitable for millimeter wave communication systems and radar systems.
