In this paper, a compact bandstop filter(BSF) based on frequency-selecting coupling structure(FSCS) is presented. The proposed BSF consists of a quarter-wavelength coupled line and a quarter-wavelength open-circuited transmission stub in shunt. For the purpose of further miniaturization, a novel structure is adopted. The performance of this filter is shown in both simulations and measurements. The stopband frequency contains 2.45 GHz and 5.8 GHz, which can be widely used in Wi-Fi, GSMand many other applications. There is a good agreement between the simulation and measurement results. The size of the proposed filter is 4.6×8.79 mm2.
