Narrative:
At the time of the error, I had 2 aircraft on frequency with very similar call signs. (Fgt xx and fgt axx). Fgt xx was sebnd at 12000 with a request for FL210. He was stopped at 12000 for traffic northbound at 13000, small transport Z. Fgt axx was at FL200 requesting FL220. After fgt axx had cleared a military refueling track I climbed him to FL220. After listening to the tape it was learned that I had transposed the call signs and actually issued a climb clearance to fgt xx resulting in loss of sep with small transport Z.
