A compact hairpin filter with stepped hairpin defected ground structure. 21st IEEE International Multi-Topic Conference (INMIC). Karachi, Pakistan, 1-2 November 2018. https://dx.doi.org/10.1109/INMIC.2018.85956349781538675366https://hdl.handle.net/20.500.12511/1604https://dx.doi.org/10.1109/INMIC.2018.8595634A compact hairpin line bandpass filter is presented with two different defected ground structures (DGS). The DGS are used to reduce the distributive response of the microstrip filter. The harmonic at 2 fo is suppressed to below -20 dB. The filter has an insertion loss (IL) greater than -3 dB and return loss (RL) of 26 dB at the center frequency, 2.4 GHz. The designed filter has a sharp roll-off and a wide band of operation. The filter is fabricated using RO4350 substrate and measured results are compared with the simulations.eninfo:eu-repo/semantics/openAccessBandpass FilterDefected Ground StructuresHairpin FilterInsertion LossConference Object10.1109/INMIC.2018.8595634N/AN/A
