What are the best methods for increase in gain and directivity in a coaxially fed patch antenna?

Please help thanks in advance :)

I am getting about 3 dB gain , improvement upto 5-6 dB is desirable. And my peak radiation is towards the right....what could be the reason ?

You can use a better substrate material with less dielectric loss, to reach the values mentioned by pragash. For higher gain, use snake oil.

Antenna pattern: maybe your model orientation in the simulator is different?

usually phi 0, phi 90, theta 0 and theta 90 will be compared to analyze radiatioN. you have all those plot?

I make 9dBi patch antennas (real dBi, not the directivity but gain with respect to isotropic; results are verified in controlled anechoic environment using Satimo tester) can even attempt to make 10dBi patch.
