Abstract: This article reports a new compact design of band-pass filter for broadband applications. It has a compact design with two bended short stubs of quarter-wavelength and a connecting stub of half-wavelength, which result in the design of a broadband filter. The filter is fabricated on silicon substrate using surface micromachining process. The fractional bandwidth of band-pass filter reported is around 0.9-4 GHz. The rejection at upper and lower pass band edge is greater than 35 dB, and the insertion loss is 2.4 dB. The area of the novel filter is (λg/4)2 at the centre frequency of the bandpass, whereas the area of the filter realized using the nonbending stubs and connecting lines is 2(λg/4)2 for the same band pass characteristics. © 2010 Wiley Periodicals, Inc.
