A novel narrowband balanced absorptive bandstop filter (BABSF) with wideband bandpass response is proposed, which consists of four coupled‐line sections with open‐circuited stubs, two half‐wavelength transmission lines, and two ground resistors. Excellent differential‐mode response with narrowband bandstop response and wideband bandpass property is realised for high frequency selectivity. Good common‐mode suppression can be achieved, rejecting the interference noise. For demonstration, a BABSF prototype operating at 2 GHz is designed with good agreement between simulated and measured results.
