Modified Inverted CSRR and Stepped Impedance Stub based Bandstop Filter with wide passband
Main Article Content
Abstract
This paper presents a compact bandstop filter (BSF) with a wide passband range (0.1 GHz – 3.7 GHz) and low insertion loss in microstrip technology. The design includes two modified inverted complementary split ring resonators (CSRRs) etched from the bottom plane and L-shaped defected structures along with two stepped impedance stubs placed symmetrically in the top plane. The stop rejected filter has a center frequency of 5.35 GHz which attenuates the signal in the C-band with a fractional bandwidth of 44 %. The designed filter has a circuit size of 0.08 lamda g square with a maximum insertion loss of 0.3 dB. The lumped equivalent circuit of the presented filter has been derived and the proposed fabricated BSF structure has also been validated finally with experimental results. This filter is applicable for ISM band (5250 MHz – 5350 MHz) and Wi-Max (2300 MHz – 2500 MHz) applications.
