Dear Amir,

Microstrip boards ae printed circuit boards which are double sided with a copper cald of two sides, The substrate material depends on the operating frequency range. For the lower frequency end FR4 is used as it is cost effective. At higher frequencies, Teflon may be used. The passive microwave components can be built from specific metal patterns on the front face of the double sided board. All the designed components are built around micro strip tans mission lines. So, transmission lines, filters, matching circuits, couplers can formed in the metal layer. Antennas can be also made.The design of these components are introduced in detail in the literature. The metal patterns are printed on the metal layers by photo lithography and etching.However there are different method to engrave directly metal patterns by mechanical removal or by LASER. For more information please see the link:http://paginas.fe.up.pt/~hmiranda/etele/microstrip_basics.pdf

wish you success

My suggestion would be towards the machines provided by LPKF (Germany) or T-Tech (US). Depending on the frquency (below 5 GHz approximately) you can build yours using etching, but beware of using nice lab techniques otherwise the results would not be alright.

See section 4.3 in my Phd thesis. It may help you. It is available in my list of publications.
