ABSTRACT Helix antenna has distinguished characteristics of radiation. Depending on its designed structure, a variety of operations may be created including linear or circular polarizations, and omni- or directional patterns. The cost and complexity will increase significantly if it is employed in the applications of antenna arrays in the manufacture and RF circuit design. This paper proposes an alternative method to realize the antenna structures based on printed circuit technologies. This method is particularly useful in the applications of array antennas at high frequencies since the wavelength is relatively small and makes the printed circuit technology suitable. The advantages are that the manufacture of the antenna subsystem may be performed at a very low cost and in an effective way. Numerical studies on the antenna characteristics are presented in this paper.
