ABSTRACT:
A distributed phase type circular polarized wave antenna is composed of a group of narrow conductor lines2a,2b,2cand2d, and the group of the narrow conductor lines2a,2b,2cand2dare laid out in a two-dimensional plane. Complex vectorial sums of respective projections of current induced in each point of the narrow conductor lines2a,2b,2cand2din two directions orthogonal to each other in the two-dimensional plane are determined, such that amplitudes of the complex vectorial sums are equal to each other in the two directions and a phase difference between the complex vectorial sums in the two directions is 90°.
