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.EnglishOctober University for Modern Sciences and Artsجامعة أكتوبر للعلوم الحديثة والآدابUniversity of Modern Sciences and ArtsMSA UniversityAntenna measurementsAntenna radiation patternsDirective antennasMetamaterialsMicrowave antennasTransmission line antennasAntenna radiationDirective antennasElectric linesMagnetic materialsMetamaterialsMicrostrip antennasMicrowave antennasAntenna measurementAntenna performanceComposite right-left-handed transmission linesDirective gainsFull-wave simulationsOpen circuitsTermination loadTransmission line antennaDirectional patterns (antenna)Conference Paperhttps://doi.org/10.1109/MetaMaterials.2015.7342446
