RF BPFs are frequently used in wireless communication applications due to their versatility, low reflection coefficient, superior selectivity and compact size. In order to improve reflection coefficient, transmission coefficient, and group delay, a compact cross shaped BPF is designed utilizing a ring resonator and a cross-shaped structure. Multi band applications is supported by this cross-shaped resonator. The dimensions of the cross shaped BPF are 12 x 34 mm2. A 50 microstrip transmission line is utilized to attach the wide band microwave bandpass filter, which is designed utilizing RT duroid 5880 with r of 2.2, of 0.0009. An-soft HFSS v13 which is based on FEM, is used to numerically design and simulate a cross shaped BPF using circular ring resonator. According to the results of the designed filter, the cross shaped BPF resonates at 11.26 GHz, 17.01 GHz, 14.28 GHz and 19.66 GHz with S21 of 0.2 dB at all resonating frequencies. Reflection coefficients of – 20.1 dB, – 33.6 dB, – 28.9 dB and – 41.2 dB with fractional bandwidths of 4.1 %, 4.15 %, 10.9 %, and 2.3 %, respectively has been observed. These results make the cross shaped BPF suitable for satellite communication applications. |
