Abstract
According to the present invention, when wireless communication is performed, a signal can be formed into a spiral beam (H), the spiral pitch of the signal can be changed, and a plurality of spiral beams (H) with different spiral pitches can be transmitted and received. The present invention pertains to a wireless signal transmitting antenna () including a signal emitting means (A) having N number of antenna elements (A, . . . , AN) (where N is an integer satisfying N≥2) equally spaced on a circumference of circle, and a signal distribution means (B) for generating, from an input first signal (S), N number of second signals (G, . . . , GN) having a phase difference from one another and outputting the N number of second signals (G, . . . , GN) to the N number of antenna elements (A, . . . , AN), respectively, so that a spiral beam (H) with the equiphase surface inclined spirally is output from the signal emitting means (A).
