摘要：A novel reconfigurable microstrip Bandpass filter (BPF) for centre frequency (f c ) 3.5 GHz is proposed in this paper . A Square ring microstrip structure with gap coupled feed has been used. A new comb-tooth structure is proposed, where combination of tooth connection is responsible for the variation of bandwidth, this scheme has been used to achieve a fractional bandwidth (FBW) variation of 0.85 to 6.48%. Further, a 3.5 GHz Square ring reconfigurable filter for five distinct bandwidth (BW) state has been fabricated for experimental verification
