For 5-pole LPF at f<jats:sub>c<\/jats:sub> = 2.5 GHz, its selectivity is 10.6 dB\/GHz and for the DGS-based Butterworth LPF it is 12.6 dB\/GHz. For the lumped elements Bessel LPF, it is only 4.84 dB\/GHz. Its 20 dB rejection bandwidth is 13.1 GHz and impedance matching BW is 76%, as against 88.8% for Butterworth LPF. At f<jats:sub>c<\/jats:sub> = 7.5 GHz, the 5-pole DGS Bessel LPF has selectivity 7 dB\/GHz, 20 dB rejection BW is 13 GHz and 10 dB return loss (RL) BW in passband is 4.86 GHz (64.8%) with less than 7.9 pS group delay (GD) variation. In case of a bulky mixed microstrip-waveguide (MMW) 5-pole Bessel LPF at 7.5 GHz [W. Menzel and F. Boigelsack, 29th European Microwave Conference, Munich (1999), pp. 191\u2013194.], reported results are: sharpness of cut-off 1.48 dB\/GHz, 10 dB RL BW and GD variation are 48% and 4 pS, respectively. The improved performance the DGS-based Bessel LPF can find applications in high speed data communication, front-end of a wideband communication system and in a power amplifier, by improving the selectivity, suppression of harmonics and linear distortion. <\/jats:p>","DOI":"10.1142\/s0218126614501229","type":"journal-article","created":{"date-parts":[[2014,7,11]],"date-time":"2014-07-11T06:19:25Z","timestamp":1405059565000},"page":"1450122","source":"Crossref","is-referenced-by-count":1,"title":["DESIGN OF BESSEL LOW PASS FILTER USING DGS WITH IMPROVED CHARACTERISTICS FOR RF\/MICROWAVE APPLICATIONS"],"prefix":"10.1142","volume":"23","author":[{"given":"Ashwani","family":"Kumar","sequence":"first","affiliation":[{"name":"Microwave Research Laboratory, Department of Electronic Science, University of Delhi, South Campus, New Delhi 110021, India"}]},{"given":"A.
