I am trying to compare basic patch antenna and antenna with defected ground plane.
Patch antenna without DGS gives resonance 2.65 and also gain 3.3db,but it shows s11 less 10 db at 4.88GHz and 6.8GHZ (but gains at these freq are in minus )
Same i have simulated pacth with DGS and following...
Thank u sir,
but normally we use only one port to feed the antenna,than how to find S21?
I just wonder why S11 is better and gain is in minus?

Thank u sir,
this big loss of what?i mean this loss is known as what name?

sorry i am new to this site so i...
i have simulated patch antenna at 2.65 ghz in hfss. i am getting s11 less than -10 db at 2.65 ghz, 4.88ghz and 6.88 but when i look at the gain associated with those freq. i get gain at 3.33 db at 2.65 ghz. but at 4.88ghz and 6.88 ghz ,i am getting gain in minus.what can be the reason for...
