    This paper introduces a new compact triple band left handed antenna. Applying a composite right left handed transmission line, and open circuit termination load, the antenna operates at triple band frequencies, 1.8 GHz, 3.5 GHz and 5.8 GHz with total size 21�25 mm2 (only 27% compared to conventional microstrip antenna). A compromise between the proposed antenna's compact size and efficiency is made, as a result the antenna provides a maximum directive gain equals 1.37 dB, 2.76 dB and 3.61 dB, respectively. The proposed antenna can serve WiMAX and GSM applications efficiently. The antenna performance is validated by full wave simulation and experimental measurements. � 2015 IEEE.
