ADS-Momentum is based on moments method (with some fast algorithms and approximations) which should be fine for these conductor based passives.
method of moment is a full wave method but ADS and IE3D not a 3D full wave as i know ADS is 2D full wave and IE3D i saw in some paper called 2.5D
patch antenna that resonate at 2.45GHz , with (length=21.9 mm , width=36.26mm,height=8mm);
I thought if we put a finite ground plan , it'll give back lobe therefore reduction of the gain,but i see that give inverse , gain is increased!!!
thank you volker , thank you all !
so i have right ! gain increase with finite ground plane !
I thought if we put a finite ground plan , it'll give back lobe therefore reduction of the gain,but i see that give inverse , gain is increased!!!
physically how we explain this!?
thank you very much!
dimension of ground plane , in general , how choose the size of ground plane ? and how this finite ground influence in parameter s11 so in resonate frequency!
