A Simple Compact Microstrip Wideband Bandpass Filter

摘要：

　　Two wideband bandpass filters with miniature size and wide stopband are proposed by using cascaded U-shaped resonators.The filters exhibit bandwidths of 31.1% and 28.8% at about 5.3GHz and 5.6GHz,respectively.Both designed filters have simple structures and compact sizes,wide passband,excellent out-band performance with wide lower and upper stopbands,and a pair of transmission zeros on both sides of passband.The new designs have evident circuit size reduction compared with relative reports.A wideband microstrip BPF is fabricated and measured,and the measurement exhibits good agreement with the prediction.
