Multiple Band Polarization Rotating Phased Array Element
WARF: P190115US01

The Invention
A multiple band phase shifter includes a first dielectric layer, a conductive layer, a second dielectric layer, and for each central operating frequency of a plurality of central operating frequencies, a switch, a plurality of vias, and a conducting pattern layer. Each via is formed of a conductive material that extends through the first dielectric layer, through a third dielectric material formed in and through the conductive layer, and through the second dielectric layer and is connected to a first throw arm or a second throw arm of the switch. The conducting pattern layer includes conductors electrically connected to a distinct via. An electric polarization of a reflected electromagnetic wave is rotated by 90 degrees when the switch is positioned in the first conducting position and the electric polarization of the reflected electromagnetic wave is rotated by −90 degrees when the switch is positioned in the second conducting position.
