Abstract
A phase shifter includes a first dielectric layer, a switch mounted to the first dielectric layer, a conductive layer mounted to the first dielectric layer, a second dielectric layer mounted to the conductive layer, a conducting pattern layer mounted to the second dielectric layer, and a plurality of vias. The switch is switchable between a first conducting position and a second conducting position. Each via is connected between a first or a second throw arm of the switch and a conductor of the conducting pattern layer. When an electromagnetic wave incident on the phase shifter is reflected, an electric polarization of the reflected electromagnetic wave is rotated by ±90 degrees compared to an electric polarization of the incident electromagnetic wave based on a conducting position of the switch. The phase shifter can be used as one-bit spatial phase shifter to provide either 0° or 180° phase shift over wide bandwidths.
