This paper reports analysis and design of bandstop filter utilizing E-shaped dual mode resonator. The basic structure of the bandstop filter consists of E-shaped resonator parallel to microstrip transmission line and an open stub inverter. Parametric analysis is carried out using micro-stripes software and the design is optimized to get stop band with high rejection level at 6 GHz centre frequency...
This paper reports analysis and design of novel tunable bandstop filter utilizing E-shaped dual mode resonator. The basic bandstop filter using E- shaped dual mode resonator is modified to a tunable bandstop filter with two discrete frequency states of 5 and 6 GHz having same fractional bandwidth of 5%. The centre frequency control is achieved by modifying the open stub inverter length using PIN diode...
