ABSTRACT:
A group of metallic conductors1are prepared and a power feed point2is formed at one of the metallic conductors to provide a circular polarized wave antenna. The circular polarized wave antenna is designed such that an absolute value of a sum of projections of an electric current induced on the metallic conductors in x-axis and an absolute value of a sum of projection of the electric current in y-axis that is spatially orthogonal to the x-axis are approximately equal to each other, and an absolute value of a difference between an argument of the sum of the projections in the x-axis and an argument of the sum of the projection in the y-axis is approximately 90°.
