A compact ultra‐wideband (UWB) bandpass filter with fixed and reconfigurable notch bands using terminated cross‐shaped resonators is proposed. Two notch bands can be realised in the passband with a fixed band and a reconfigurable band. The reconfigurable band can be adjusted by changing the terminated loaded capacitance. The UWB passband is realised by three parallel coupled lines, and the notch bands are realised by using terminated cross‐shaped resonators.
