I have designed a dipole antenna.
But I want to re-use the antenna resonating at the same frequency(866MHz) but with different gain.
What can be done to acquire the scenario using the same set-up?
If you have designed a dipole antenna with a gain of 6dB then it has tobe patented.Because nominally gain of an antenna is around 2dB.i dont know how you came up with that number.

Sorry! I was wrong with my statement. I guess whatever Peak Gain shown in "Calculate Antenna parameters" is in dBi.
If I have restricted transmit power of 1W but if I need to achieve of EIRP of 4, what should I do?
The only thing within my hands is to design antenna with a Gain of 4 or 6dBi.
Please help me out.

To get any more gain than the 2.5dBi from a dipole is going to require a more complex antenna built around the dipole.
For omni directional you could use a colinear which is basically a set of stacked 1/4, 1/2 or 5/8 wave elements and for ~ 800MHz gains up to 10dBi would be relatively easy to achieve.
If you dont need omni directional and are happy with a directional system then you would use antennas like corner reflectors and Yagis.
A corner reflector with 1 wavelength sides will give ~ 10dBi gain
A 3 element Yagi will give ~ 6dBi gain
BUT I clarify to you again You are NOT going to get more than ~ 2.5dBi out of a single dipole,
