have you used passive design guide ?
just explore it.

No I didn't...as I'm new to this ADS Software, I would like to know more in it.....
Could you please help me where do I find the passive design guide.....

Thanks a lot for your reply.....

You can access the passive circuit design guide from the top menu >DesignGuide>Passive Circuit.

After u click it opens the Passive Circuit Design Guide control window.From this window click the icon Component Palette MicroStrip Circuits.When you click it the component selection menu automatically appears in the design window.Place the one of the coupler types to schematic.After this place your dielectric material and set the smart component values i.e frequency,delta etc. Then select your smart component in the Passive circuit Design guide control window and click Design Asistant tab > Design. The software automatically synthesise your coupler from the specifications that u gave.Then use simulation assistant tab to simulate your results. That is all.
