sadjid thank u very very much for ur help ,
I want to ask you some questions if you allow(exuse me i use google translator)
1-50 Ohm line how you find its length?
2-I find me these dimensions:
patch:Lp=27.5 mm -Wp=36.26 mm
quarter wave line: Lq=46 mm , Wq=0.16mm
in ADS momentum : I did the simulation with these two components , and the port that is given by the software momentum play the role of line 50 ohm ,dont need to design a 50 ohm line , and i obtain a good result (s11=-34 db in fr=2.4GHz) , What do you think ?
