please suggest me a NFC transmitter circuit?

 

If I may suggest some older NFC projects,
http://cappels.org/dproj/minmassrf/Min_Mass_Wireless_Coupler.html

And some projects using those circuits:
http://cappels.org/dproj/minmassrfbase/minmassrfbu.html
http://cappels.org/dproj/minmassrfM8/minmassrf8.html
http://cappels.org/dproj/minmassrffm/minmassrffmtr.html
http://cappels.org/dproj/minmassrfTruly/mmrft.html
http://cappels.org/dproj/minmassrfloop/loopantring.html

And of course, you can find many more with a quick Google search of "near filed communications"
