Design Helix Antenna by using HFSS

ABSTRACT the aim of this paper is to providing actually a current of implicit wireless displacement sensor. The sensor consist of outside helix antenna and an inside aluminum oxide strip (AOS) material. Agreement with the perturbation theory, which there is an imprecise linear relation ship between the transfer of AOS material in the hollow of the helix antenna & resonant frequency of the last. Owing to the configuration of the sensor. In this paper, at first designed the configuration by using MATLAB software program just only the helix antenna, then adding the AOS material strip to the helix antenna. Second step is to study the numerical analysis and mythology measurable factor forming, the both last are conveyed through high frequency structure simulator (HFSS) of the helix antenna without the material AOS, at last step we adding the AOS to the helix antenna. Then design areal helix antenna by using copper material. The evaluation result achieved that the sensor of the determined range has good linearity and sensitivity
