摘要

The present invention is a wireless signal transmission antenna (10) that has: a first wave source (11), which has a plurality of antenna elements (A1-AN), and forms, by means of the antenna elements (A1-AN), a first helical beam (H) for orbital angular momentum (OAM), and outputs the beam; and a second wave source (15), which receives the first helical beam (H), and forms a second helical beam (L) to be outputted in the fixed direction. With the wireless signal transmission antenna (10), the helical beam (L) for OAM can be transmitted, device configuration can be simplified, and the size of the device can be reduced.
