In UHF RFID (radio frequency identification), passive tag antennas can be fixed on boxes or recipients where the nature and contents might vary. These variations strongly affect the antenna performance. A combined antenna is proposed to ensure an effective read‐range for a plastic recipient containing water or not. Two separate antennas are first designed for the filled and unfilled cases, respectively, then combined for a correct working in both configurations.
