ABSTRACT:
A distributed phase type circular polarized receiving module provided with a plane, a power feed point4formed on the plane, and a group of narrow conductors101having a substantially one-dimensional current distribution, and the narrow conductors being distributed in two dimension on the plane, a transistor9connected to the power feed point4, sums of projections of complex vectors of current distributions induced on the narrow conductors101in first and second directions orthogonal to each other defined on the plane are determined in amplitude and phase, such that amplitudes are approximately equal to each other and a phase difference is approximately 90°.
