ADS

(OP)
Anyone,
Do you think we can design phased array antenna using ADS advanced design system? I was wondering how to design the antenna part i.e dipole, patch, microstrip antenna. For your info I've never used ADS before, some people tell me it is useful for designing RF system, antenna etc.
Any website give a guide to use ADS?

RE: ADS

I haven't seen any web info.  I went to an ADS training session in Dallas, TX USA about six years ago and it was very helpful.  I haven't used ADS in about four years now so I'm rusty, but I expect it is a good tool for your purpose.  

RE: ADS

Can't use ADS for antenna design. You need Ansoft HFSS, or CST Microwave Studio.
Individual antennas are easy to design using many software packages but an array design can be complicated due to scan blindness concerns. Either of these two expensive ($40K US) software programs work to design antenna arrays.
Arrays often (90%) get blind spots (i.e. 20 dB gain dips) when you scan them to wide angles. Blindness is due to mutual coupling between the antennas in the arrays.Scanning to narrow angles off antenna broadside have less problems.
A single patch antenna is 20% larger in size than the same frequency patch antenna used in a large array scanned out to 60 degrees. Hence if you have simple software that designs a patch antenna alone, and you place it in an array (with elements spaced 1/2 wavelength), the efficient operation frequency of that array may be 10-20% lower than you wanted.
