A Novel Planar Microstrip Antenna Design for UHF RFID
Madhuri Eunni, Mutharasu Sivakumar, Daniel Deavours
Passive UHF RFID tags generally do not work well near metal or water. Microstrip antennas offer a potential solution, but suffer from manufacturing complexity because a need for via or some other reference to ground. We present a new antenna and matching circuit design using a balanced feed that eliminates any reference to ground and thus simplifies the antenna’s construction.
