摘要: An ultra-wideband (UWB) bandpass fllter (BPF) with hybrid coplanar waveguide (CPW)/microstrip structure is introduced in this paper. Then a pair of lowpass fllters integrated on the CPW feed lines to achieve good out-of-band rejection. At last, notched band two transmission zeros realized at 5.8GHz by using symmetric E-shaped slot-line and etching slots microstrip resonator. Two are desired band, out-of rejection more than 32dB. In order prove validity, proposed fabricated measured, measured results agreement simulated ones.
