| Abstract: | A Chebyshev band-pass filter of coplanar waveguide (CPW) structure is designed by using gaps as the impedance inverters. The values of the inverters realized by different CPW gaps have been calculated using electromagnetic simulator software. Based on this, design of a 3-pole Chebyshev CPW filter using YBaCuO thin film and its optimized performance has been presented. |
