The invention provides a damage resistant antenna using a super-elastic flexible metallic material to form antenna radiating structures with a high damage threshold. The invention accounts for the electro-magnetic properties of the super-elastic flexible metallic material in the design of the shape and dimensions needed to form antenna radiating structures with consistent performance after repeated deploy, stow, and transport cycling of the antenna.

Damage resistant antenna

A method for determining a physical property of an object or fluid in a dynamic multi-path clutter environment comprises transmitting an RF interrogation signal to a wireless sensor physically coupled to the object or fluid (gas or liquid) in the dynamic multi-path clutter environment, wherein the wireless sensor is operable to receive the RF interrogation signal, produce a reference signal and a measurement signal, and retransmit the reference signal and the measurement signal in the dynamic multi-path clutter environment. The reference signal and measurement signal are delayed by the wireless sensor by an amount of time that may be a function of the unknown physical property. The method also comprises receiving the retransmitted reference signal and the retransmitted measurement signal and comparing them in the time domain in order to determine the unknown physical property of the object or fluid. The method further comprises setting the time delays of the retransmitted reference and retransmitted measurement signals to be long enough for the ringdown time to be over but not so long so that the differential time is distorted by the dynamics of the system.
