This introduced topology proposes triple band for 7.4 GHz, 9.2 GHz, and 13 GHz with insertion loss 2.3 dB, 0.6 dB, and 0.55 dB, respectively. Moreover, the return losses are equal 13 dB, 43 dB, and 10 dB, respectively. The paper elaborates the equivalent circuit model, analytical study and 3D full-wave simulation. Furthermore, the design realizes compactness size (13.2 � 5.9 mm2). The quality factor demonstrates selectivity equals 35, 8.18, and 48.1 at the four bands, respectively. � 2016 IEEE.EnglishOctober University for Modern Sciences and ArtsUniversity for Modern Sciences and ArtsMSA Universityجامعة أكتوبر للعلوم الحديثة والآدابCoupled gap resonatorD-CRLH resonatorsLriple band resonatorMetamaterial resonatorEquivalent circuitsStructure (composition)Analytical studiesComposite right/left-handedEquivalent circuit modelFull-wave simulationsMicrostrip structuresQuality factorsReturn lossTriple bandResonatorsConference Paperhttps://doi.org/10.1109/MECAP.2016.7790118
