Hi Saka Ji,

Return Loss is influenced by the impedance matching of the antenna with the feed.

Try to get the Zin (Z11) Curves and see if there is an impedance match at the desired point of frequency.If not then re adjust the CPW feed structure.

Hope that gives you a solution.

I think the problem is with SMA connector. because when I exited the antenna with wave port it gave me good results. now I want to produce the same result using an SMA connector. please give suggestions related to SMA connector.

any suggestions ?
