Abstract

The present invention is a radio signal transmitting antenna () including a first wave source () including a plurality of antenna elements (Ato AN) configured to form a first helical beam (H) for OAM (Orbital Angular Momentum) from the plurality of antenna elements (Ato AN) and output the first helical beam (H) and a second wave source () configured to receive the first helical beam (H) and form a second helical beam (L) output in a constant direction and transmits the second helical beam (L). The radio signal transmitting antenna () can transmit a helical beam (L) for OAM with a simplified and smaller device configuration.
