To achieve this, a free-space matched RFID antenna is studied and modifications are made in order reduce its size drastically and to turn it functional when applied to a bottle with water. Later, range measurement tests are made on the fabricated tag.engRFIDTagUHF RFIDRFID tags on bottlesImpedance matchingAntenna size reductionconference object10.23919/EuCAP53622.2022.9768888
