An Offset-fed Orbital Angular Momentum Transmitarray Antenna for Millimeter Wave Communications
A square aperture wideband transmitarray antenna (TA) with orbital angular momentum (OAM) pattern for millimeter communications is analyzed and designed. The subwavelength element consists of two parts: the polarization grids and the phase shift element that is an open resonant ring with a 45°-twisted angle. The top and bottom metallic layers are grids which are orthogonal to each other. Simulation results show that an ideal OAM beam can be successfully obtained. With the elaborate design, a peak gain of 19.2 dBi, and a −1 dB gain bandwidth of 13.56% ranging from 55 to 63 GHz are achieved.
