Patent ID: 7633444

Claim:
A distributed phase type circular polarized receiving module, comprising: a power feed point and a first group of narrow conductors having a substantially one-dimensional current distribution being formed at a common plane as a first plane, the first group of narrow conductors being distributed in two dimensions on the first plane; and a transistor connected to the power feed point; a second group of narrow conductors having a substantially one-dimensional current distribution formed at a second plane, the second group of narrow conductors being distributed in two dimensions on the second plane; 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 and second planes are determined in amplitude and phase, such that amplitudes are approximately equal to each other and a phase difference is approximately 90°, wherein the power feed point is provided at a position where an input impedance of the antenna is complex conjugated with an input impedance of the transistor.
