Abstract
wideband linearly-polarized unit cell for beam-steering transmitarray based on polarization rotation is proposed. As beam-steering capability is important for 5G/B5G communication, in this work, PIN diodes are used to modify the design proposed in [1], resulting in a reconfigurable 1-bit unit cell. Besides, a central slot has also been added to the top and bottom layers to improve matching, and an additional thin layer of substrate has been added for DC routing. The proposed unit cell achieves a fractional bandwidth of 18.7% under the criteria that reflection coefficient is less than -10 dB and phase difference is within 180° ± 10°. Also, the insertion loss is less than 1.6 dB throughout the entire operating band.
