Abstract: A sensor according to the present disclosure may include a substrate, an antenna pattern formed to transmit and receive a wireless signal to and from an external device, a sensing unit configured to be driven when the wireless signal is received through the antenna pattern and to generate a signal when in contact with a sensing target material, and a circuit line electrically connected between the antenna pattern and the sensing unit, wherein the antenna pattern and the circuit line are formed of a same material and on a same layer. A fabrication method of a sensor according to the present disclosure may include printing a conductive layer having an antenna pattern, a sensing electrode and a circuit line on one surface of a substrate with a single layer, heat-drying the conductive layer, printing, on a single layer, a circuit insulating layer that covers part of the circuit line and an antenna insulating layer that covers part of the antenna pattern, curing the insulating layer, printing an antenna bridge on the antenna insulating layer, heat-drying the antenna bridge, and bonding a device electrically connected to the circuit line to the substrate.
