Abstract

This application belongs to the field of antenna technology and relates to a polarization rotation unit and a beam reconfigurable array antenna. The polarization rotation unit includes a patch layer, a dielectric layer, and a control layer. The patch layer includes a first radiating patch and four spaced arrays of second radiating patches. The first radiating patch is square, and any diagonal of the first radiating patch forms a 45° angle with any diagonal of the dielectric layer. The second radiating patches include two or more rectangles of different sizes, with two sides of any adjacent rectangles collinear, and each rectangle is axially symmetric about one diagonal of the dielectric layer. The first radiating patch and each of the second radiating patches are connected by diodes, with diodes in the same direction having the same direction and diodes in different directions having opposite directions. The control layer is connected to the patch layer to control the on and off states of each diode and supports programmability. This application can realize polarization rotation and state reconfigurability.
