Your chances of success will be small unless you show measured results.

If gain varies 7.6 dB in 72 deg scanning angle, then you cannot claim 72deg scanning angle. Your scanning angle range is that within which gain does not drop more than 3 dB. Also, it is important that your side lobe level is better than -10 dB.

in your design the variation gain is more than 3 dB this is not acceptance in most of communications systems

It all depends upon the theory that you will present in your paper. If you will give some novel design techniques then definitely chances of your paper getting selected in good journals increases....
