Patent ID: 7460068

Claim:
A distributed phase circular polarized wave antenna, comprising: a power feed point; a first conductor plate comprising a plurality of narrow conductors having a substantially one-dimensional current distribution and distributed in two dimensions; a second conductor plate comprising a plurality of narrow conductors having the substantially one-dimensional current distribution and distributed in the two dimensions; and a coupling conductor for connecting the first conductor plate and the second conductor plate, wherein the power feed point is provided such that a grounding potential is connected to one of the narrow conductors composing the first and second conductor plates and an excitation potential is connected to another of the narrow conductors composing the first and second conductor plates, and wherein sums of projections of complex vectors of current distributions induced on the narrow conductors in first and second directions orthogonal to each other defined on the first conductor plate and second conductor plate are determined in amplitude and phase, such that amplitudes are approximately equal to each other and a phase difference is approximately 90°.
