Temperature sensing device for sensing aircraft wheel brake 200 temperature, the temperature sensing apparatus 300 comprising a surface acoustic wave, SAW, sensor element; and a planar sensor antenna electrically coupled to the SAW sensor element, the planar sensor antenna for receiving an interrogation signal and transmitting an output signal that is responsive to the interrogation signal, wherein the planar sensor antenna comprises two loops of a conductor material, the loops disposed on a surface of a substrate to provide the planar sensor antenna. Preferably the sensor element also comprises an interdigital transducer, IDT, and the planar sensor antenna is electrically coupled to the IDT. The sensor element may also comprise an input IDT and an output IDT with the planar sensor antenna is electrically coupled to both. A brake disc 202 comprising the temperature sensing device attached to the brake disc, an aircraft comprising the brake disc and a method of manufacturing a temperature sensing device is also claimed.
