Abstract

This paper presents a dual-band bandstop filter by using two hook shaped stepped impedance resonator. The filter structure consists of main transmission line and two three-section stepped impedance resonators are connected to this line. Transmission line contains two open stubs to give improved passband return loss and rejection bandwidth. The resonant frequency and bandwidth of the filter can be flexibly controlled by changing the length and position of high-Z and low-Z segments. The design modeling and methodology are also delivered for the efficient design. Two center frequencies at 2.2 GHz and 5.2 GHz is present with rejection level upto 54 dB.The FR4 epoxy material has been used for the design having dielectric permittivity of 4.4 and a thickness of 0.8 mm, which is easily available in market with nominal cost.
