The miniaturized proposed antenna (30 {\~A}? 30 mm2) comprises two layers of polyimide as a substrate with a dielectric constant of 3.5 and a thickness of 0.125 mm. Furthermore, a tree shape transmission line and two rounded rectangular patches use Indium Tin Oxide (ITO) as a transparent conducting film while they are proximity coupled. The patches are cut by two rounded rectangular and J-shape slots to improve the radiation efficiency of the antenna. Besides, all antenna's parts are formed to obtain radiation efficiency {\ensuremath{>}} 83 at all the resonances, the gain of 3.27 dBi, 9.47 dBi, and 4.47 dBi at 2.45 GHz, 3.8 GHz, and 5.7 GHz respectively. Besides, the antenna shows a good agreement between simulation and measured results. {\^A}{\copyright} 2020 IEEE.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85096653591&doi=10.1109\%2fBlackSeaCom48709.2020.9235009&partnerID=40&md5=a94c41bdaa09564da36522963942c603} }
