Design a microstrip bandpass filter using ADS 1.575GHz for GPS receiver

[khungbopro]

Hi everyone,
Can you help me to design a band pass filter using ADS and microstrip technology. The parameters of the band pass filter are:

1. Center frequency: 1.575GHz
2. BW=50MHz

and the following is parameters of the substrate:

1. εr=4.6 (Fr-4)
2. H=1.59 mm
3. T=0.035 mm
4. Tand=0.02
5. Match Impedance = 50 Ohm
In addition, can you tell me the way to caculate the parameters of components in you design (ex: W, L of MLIN...)

Thank you very much and looking to hearing from you soon.

If you use this substrate with that bandwidth, insertion loss will be very high.
Consider higher permitivity..
