Report on Microstrip filter design using the stubs and transmission lines techniques

I, along with my friends, did a small project on Microstrip filter design using the stubs and transmission lines techniques during my Microwave course. The project was developed on AWR Mircowave office and was tested on Vector Network Analyzer. Following is the specification of the project:

To design a Low Pass filter, 0.5dB Equal-ripple, fc=2.4GHZ, R0=30Ω, Insertion loss at f=3.6GHZ is -5dB. Implementation of the filter using stubs and transmission lines technique with equal electric length transmission line segments (lambda/8)

The following are the detailed summary of the goals

  • To design the filter theoretically
  • To simulate the designed filter and check its performance
  • To implement the designed filter using microstrip technology
  • To check the performance of the filter on the 2 port network analyzer

    This was very much inspiring and i am too thinking of making a similar filter design. My doubt is that how did you obtain the final layout of the filter. And what type of file did you gave the pcb manufacturer to etch the circuit.

      Hi Aviraj,

      I used the AWR Office tool for designing the filter. If you look at the report you will see how the final layout was obtained. I printed out the layout with specification and gave it to lab in-charge.

        But did you get the final layout (in the black and white format) in AWR office itself or did you use some other software?

          Hmm.. It was almost two years back… As far as my memory goes, I did not use any other software or tool.

            Thank you for your help… I will try it with AWR Office then,,, :)

              Good luck with that.
