Dual Circularly Polarized All-Metal Orbital Angular Momentum Beam Reflectarray Antenna
This paper presents an all-metal, dual-circularly polarized OAM beam reflectarray antenna operating at 30 GHz. A 15λ0×15λ0 OAM reflectarray having F/D ratio of 0.6 is designed to produce Bessel beam with mode number, l = 1, and cone angle of 15°. The reflectarray consists of a low-loss square-shaped metallic unit cell independent of the polarization of the incident waves. The dual-circular polarization is achieved using a pyramidal feed horn antenna with a square septum polarizer. The feed offers polarization diversity by switching between the two input ports of the septum polarizer.
