Patent ID: 7012327

Claim:
A phased array antenna system comprising: a plurality of sub-array modules integrated together to form the phased array antenna, and at least one amplifier connected to the plurality of sub-array modules, each of the sub-array modules being comprised of a plurality of radiating elements, each of the radiating elements including: a first module comprised of a first plurality of low-temperature co-fired ceramic (“LTCC”) layers forming at least one first circuit used in the operation of the phased array antenna; a second module comprised of a second plurality of LTCC layers forming at least a second circuit used in the operation of the phased-array antenna; at least one radiating patch formed on the second module; and at least one phase shifter fabricated from at least one microelectromechanical (“MEMS”) switch and formed between the first and second modules; and wherein the second module is bonded to the first module so as to enclose the at least one MEMS phase shifter between the first and second modules.
