摘要: A compact ultra-wideband (UWB) bandpass filter (BPF) with notched band and improved out-of-band performance is presented. In the design, UWB built up using hybrid microstrip coplanar waveguide (CPW) structure. Open stubs are embedded on bottom of to realize narrow which reject undesired wireless local-area network (WLAN) radio signals. The center bandwidth can be controlled by adjusting length width stubs. cross-shape patch constructed implement transmission zeros in upper so as suppress first spurious passband. proposed has merits size, flat group delay, good insertion/return loss, selectivity.
