Help me with the graph

Hello everyone, i am doing a simulation and i got a characteristics for s11 as shown in the image

Just tell me what all p

oints i can write in the report from the graph..

your frequeny is 3.934GHz at that frequency magnitude of ur singnal is -23.084. i dont realy come to no which signal is this..X-is time or frquency y-is your magnitude which is in dB(desibel) unit.

well that i understood...but my doubt is when i write the report on the simulation result what all things i should write...please respond

For accuracy I would write about both resonance points you get.

can you be more elaborate.. i meant i want to include it on my thesis...tats why

I mean, you cannot ignore parasitic resonances you get at other frequencies than those you are looking for.
So, write in your thesis that sweeping the S11 frequencies from 1GHz to 6GHz you get what the simulator shows in the picture.
I don't know your circuit, but analyzing carefully you can identify the reason of the parsitic resonance that you get (could be the PCB layout, bias decoupling, bias circuit, SRF of come capacitors, and so on).

well i am working on the metamaterial structure and this is what i got when i simulated the structure in ads momentum and so you meant that the parasitic resonance occur at 3.94 Ghz..am i write...please explain...well wat all points i can add
