Minimization techniques are adaptations of Helical structure, Meta material, multi-layer structure etc. But, Helical structure is not suited to minimization technique of RF circuit having single resonant frequency. Because it generate resonant frequency following as rotation of circumference. Meta material and multi layer structure have weakness of expenditure and complex structure. In addition, conventional three dimensional Mobius Strip and planar Mobius Strip are not two dimensional planar Mobius Strip that has weakness of electrical coupling effect. Therefore, in this paper, we proposed miniaturized and reduced electrical coupling effect antenna by adaptation of Quasi Mobius Strip that topology is same as three dimensional Mobius Strip with Via-Hole structure. According to the simulation result, physical circumferential length is 1/3 minimized compared with conventional ring antenna under the same resonant frequency. In addition, coupling effect is not nearly generates near to the resonant frequency, 2.4GHz.
