Aircraft sensors are described which record a condition of interest of the aircraft during flight without being powered. The sensor may include a sensing element comprising a nanostructure material which permanently changes state in connection with a permanent change in state of the aircraft, thus recording the condition of the aircraft. When the aircraft is on the ground, the recorded condition is read from the sensor using a wireless radio frequency (RF) reader, rather than communicating the recorded state during flight. In this manner, the sensor operates without interfering with the aircraft while in flight.

Embodiments of the present disclosure relate to a UAV comprising a fuselage, a rotor, and a patch antenna element. The patch antenna element, which is provided from a patch antenna stack-up, is conformally disposed on an outer surface of the UAV's fuselage.
