A phase shifting array antenna includes antenna elements that have a non-electrically conductive substrate having first and second sides, an electrically conductive patch formed on the first side of the substrate, and a ground plane formed on the second side of the non-electrically conductive substrate. At least two pairs of integrated microelectromechanical switches are arranged diametrically opposed across the patch on the first side of the substrate, each microelectromechanical switch having a first electrode electrically coupled to the patch and a second electrode electrically coupled to the ground plane, the first and second electrodes being operable to be capacitively coupled, thereby creating a short circuit plane across the patch. A sealing structure hermetically packages the microelectromechanical switches.
