    Abstract: The invention concerns an RFID sensor device (1, 2, 3) for tires, designed to be embedded/integrated, at least partially, in/into, or applied to, a tire (4) and comprising a patch-type antenna that includes a multilayer structure comprising: a bottom ground plane (10, 20, 30); an intermediate dielectric substrate (11, 21, 31) arranged on the bottom ground plane (10, 20, 30); and one or more top conductive patches (12, 13, 22, 32) arranged on the intermediate dielectric substrate (11, 21, 31) and covering partially or completely said intermediate dielectric substrate (11, 21, 31), wherein said bottom ground plane (10, 20, 30) and said one or more top conductive patches (12, 13, 22, 32) are short-circuited or capacitively coupled. The RFID sensor device (1, 2, 3) further comprises: a rigid or flexible board (15, 25, 33) arranged on said one or more top conductive patches (12, 13, 22, 32) and/or the intermediate dielectric substrate (11, 21, 31); an RFID chip (16, 26, 34) installed on the rigid/flexible board (15, 25, 33) and connected/coupled to said one or more top conductive patches (12, 13, 22, 32); a temperature sensor integrated into, or connected to, said RFID chip (16, 26, 34); and a pressure sensor (17, 27, 35) installed on the rigid/flexible board (15, 25, 33) and connected to the RFID chip (16, 26, 34). The bottom ground plane (10, 20, 30) 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 (4). The intermediate dielectric substrate (11, 21, 31) is made at least partially of rubber, or is formed at least partially by dielectric and/or rubber elements/layers of the tire (4).

    Abstract: A patch radiofrequency identification (RFID) device for tires comprises: a substrate; a first insulating layer covering part of the substrate; an RFID chip and first antenna connected to each other and arranged on the first insulating layer; a second antenna electromagnetically coupled with the first antenna and extending, at least partially, on the first insulating layer. Part of the second antenna extends around the first antenna and includes two ends located at opposite sides thereof, and another part includes one or more arms extending in opposite directions from the first antenna, the arms being respectively formed by meander-line-shaped and/or spiral-line-shaped wire. The RFID chip, the first antenna, and the second antenna lie on a same plane. The second antenna is a parasitic radiator. A second insulating layer covers the first insulating layer, the RFID chip, the first antenna and, at least partially, the second antenna.
