Abstract
The invention concerns an RFID sensor device () for tires, designed to be embedded/integrated, at least partially, in/into, or applied to, a tire () and comprising a patch-type antenna that includes a multilayer structure comprising: a bottom ground plane (); an intermediate dielectric substrate () arranged on the bottom ground plane (); and one or more top conductive patches () arranged on the intermediate dielectric substrate () and covering partially or completely said intermediate dielectric substrate (), wherein said bottom ground plane () and said one or more top conductive patches () are short-circuited or capacitively coupled. The RFID sensor device () further comprises: a rigid or flexible board () arranged on said one or more top conductive patches () and/or the intermediate dielectric substrate (); an RFID chip () installed on the rigid/flexible board () and connected/coupled to said one or more top conductive patches (); a temperature sensor integrated into, or connected to, said RFID chip (); and a pressure sensor () installed on the rigid/flexible board () and connected to the RFID chip (). The bottom ground plane () is formed: by conductive textile/fabric/thread/fiber/yarn elements/layers or by a metal weft/net/mesh; or at least partially by conductive and/or metal elements/layers of the tire (). The intermediate dielectric substrate () is made at least partially of rubber, or is formed at least partially by dielectric and/or rubber elements/layers of the tire ().
