This paper investigates the properties and application of structured radio beams using phase-controlled radio-frequency (RF) antenna arrays. First, is an investigation of a unique, structured, mixed-frequency radio beam carrying orbital angular momentum (OAM). EM beams with OAM exhibit self-healing properties in the optical realm, which extends to radio communications, sensing, and combined radar-communications. Airy beams also self-heal, and have free-accelerating properties. Reproducing these properties via small phased antenna arrays enables remote sensing applications, including phase-controlled leveraging of the parabolic trajectory. Results from laboratory experiments over 0.7 to 6.0 GHz as well as results from numerical simulations are presented.
