The invention relates to an RFID sensor device (1, 2, 3) of a tyre, designed to be at least partially embedded/integrated or applied to a tyre (4) and comprising a patch-type antenna having a multi-layer structure, the multi-layer 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 partially or completely covering the intermediate dielectric substrate (11, 21, 31) wherein the bottom ground plane (10, 20, 30) and the 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/flexible plate (15, 25, 33) arranged on the 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) mounted on the rigid/flexible plate (15, 25, 33) and connected/coupled to the one or more top conductive patches (12, 13, 22, 32); a temperature sensor integrated to or connected to the RFID chip (16, 26, 34); and a pressure sensor (17, 27, 35) mounted on the rigid/flexible plate (15, 25, 33) and connected to the RFID chip (16, 26, 34). The bottom ground plane (10, 20, 30): is formed from an electrically conductive fabric/cloth/thread/fiber/yarn element/layer or from a metal weft/mesh/mesh; or is at least partially formed by an electrically conductive and/or metallic element/layer of the tyre (4). The intermediate dielectric substrate (11, 21, 31) is at least partially made of rubber or at least partially formed by dielectric and/or rubber elements/layers of the tyre (4).
