1. A microelectromechanical system (MEMS) steerable electronically scanned lens array (ESA) antenna, comprising:

  • a wide band feedthrough lens including first and second arrays of wide band radiating elements, and an array of MEMS phase shifter modules disposed between the first and second arrays of radiating elements; and

    , a continuous transverse stub (CTS) feed array disposed adjacent the first array of radiating elements for providing a planar wave front in the near field;

    wherein the MEMS phase shifter modules steer a beam radiated from the CTS feed array in two dimensions.
