The present invention introduces the use of a carbon nanotube-based material in the production of phased array patch antennas of various shapes and sizes including slot and spiral patch antennas. The use of this material provides the ability for the antennas to withstand high-intensity shock vibrations and other intense disturbances and continue emitting phased array signals. Furthermore, the use of this material for patch antennas allows for the alteration of the desired frequency and directional degree of interest by simply energizing various elements within the carbon nanotube-based material.
