摘要: A novel ultra-wideband bandpass filter based on a back-to-back microstrip-CPW transition structure is presented. The composed of two transitions and section microstrip line used as multiple-mode resonator. has been investigated numerically experimentally. Both simulated measured results show that the good performance, including small insertion loss, group delay variation less than 0.2 ns, stopband up to 16.0 GHz at high frequencies, an out-of-band rejection level below -20.0 dB.
