Abstract
The analysis of two designs of bandpass filters using substrate integrated waveguide (SIW) and microstrip patch transitions are presented. The SIW based 2nd order filter is having two transmission zeros from 12 to 18 GHz range with a 50-Ω input impedance. By four metallic walls, two-cavity resonators are created to obtain the filtering characteristics. In the second design using patch transition arrangements with a semicircular patch added with stubs, the filtering performances are suitably characterized. The maximum measured fractional impedance BW is 49.66% for Design 1 and 22.74% for Design 2, respectively. The maximum insertion loss (IL) is 0.22 Db using the SIW, technique. Group delay (GD), phase delay (PD), impedance bandwidth (IBW), scattering parameters, and return loss are verified. A comparison analysis is presented showing the designs are suitable candidates for Ku-band X-band applications.
