Abstract: An RFID tag arrangement (1) comprises a first (20; 20'; 20''; 20''') and second (30; 30'; 30''; 30''') antenna, each comprising an intermediate feeding part (23; 23'; 23''a, 23''b; 23'''a, 23'''b and 33; 33'; 33''a, 33''b; 33'''a, 33'''b) and two radiating dipole elements (21, 22; 21', 22'; 21'', 22''; 21''', 22''' and 31, 32; 31', 32'; 31'', 32''; 31'', 32''') connected to the intermediate feeding part and extending in different directions. An RFID chip (24) is electrically coupled to each of the intermediate feeding parts. The radiating dipole elements of the two antennas are arranged at a distance from each other, and the intermediate parts are arranged to cross each other at least one crossing point. A dielectric separation layer (4, 5) is arranged between the first and second intermediate parts at said crossing point(s), thereby galvanically separating the first antenna from the second antenna. Hereby, a versatile RFID tag arrangement with very good omnidirectional performance is obtained. A corresponding production method is also provided.

Abstract: An antenna (1) for an RFID (Radio Frequency Identification) tag (100) comprises two antenna parts (11a, 11b) being arranged at opposite end areas of the antenna, and at least one intermediate part (12) forming a bridge between the antenna parts. One of the at least one intermediate part comprises power feeding areas (13a; 13b) to be connected to an integrated circuit (3). Further, a first gap (14; 14b) is arranged in one of the at least one intermediate part, and has a gap length of less than 80 μm, which forms a low impedance path for current at microwave frequencies.
