How to make the result similar?

I would like to do the E shape patch antenna. However the result is different from me. I would like to make my result (the colourful one) similar to the result (black one). How can I do it? Can anyone help me? Thank you

Hi sunnyfunghy,
which result u trying to simulate. solid line or dotted line. seems to me its a solid line. You dint attached the paper with this but I think you need to check the matching impedance. Is it 50 ohms or something else?? check it. result should come as shown.. Hope it helps.

Regards
