| Summary: | The purpose of this project is to design, simulate and fabricate a microstrip Chebyshev bandpass filter. There would be two designs, which the ideal and designed filter, from these two, the designed were compared and justified whether it will suitable and operable in K-band frequency range. The bandpass filter should be operates in 21-21.3 GHz, which is 0.3 GHz in bandwidth. The filter would have 0.1 dB passband ripple, -30 dB attenuation at 22 GHz. The microstrip antenna was designed and simulated using GENESYS and measured using Vector Network Analyzer (VNA). In this design, Rogers RT Duroid 5870 has been used as a substrate with 0.5 mm height, relative dielectric constant, sr = 2.33 and dielectric loss tangent of 0.001. The measurement results doesn't give the expected result, however it give a good result that the microstrip properties tested in this design were not suitable for the frequency high as K-band range. |
