Design of microstrip lowpass filter at 3 GHz for wireless communications / Normasni Ad Fauzi
The purposes of this project are to design, simulate, fabricate and measuring the output response of the Microstrip Lowpass Filter. The filter is intended to operate with cut-off frequency of 3 GHz, a stopband attenuation of 30 dB and 0.5 dB of passband attenuation. The ripple passband is to be 0.04...

| 总结: | The purposes of this project are to design, simulate, fabricate and measuring the output response of the Microstrip Lowpass Filter. The filter is intended to operate with cut-off frequency of 3 GHz, a stopband attenuation of 30 dB and 0.5 dB of passband attenuation. The ripple passband is to be 0.0432 dB. The major design process is aided by CAD packages called HP/Eesof Libra and Sonnet Lite. The microstrip laminates used as 'Duroid/Rogers 5872' with 0.5 mm substrate thickness and relative permittivity ^r equal to 2.33. The filter is then measured using a Wiltron Scalar Network Analyzer to obtain its characteristics. |
