Improve efficiency in CST model

Hi,
I am new in CST design. I have designed a model from gerber and simulated antenna. After a number of tuning I got better return loss (-15.5dB), but radiation efficiency is not so good (-2.239dB). I tried to improve the result (almost near to zero) by changing the antenna length, but result is always around -2dB. So what parameter I should change for better radiation efficiency?
Note: I can not change layer thickness, material, dielectric etc... only I need to work antenna length or width.
I am using Trace antenna and it looks like letter "J". Sorry due to company policy I can not share my design here.
Thank you.
