Abstract
A unidirectional moxon antenna for UHF RFID tags is proposed. Meander lines are applied in this structure for the size reduction. An inductively coupled feeding loop is used to match the impedance between the antenna and the chip. A gain of 4.48 dBi and an outstanding front-to-back ratio of 17.7 dB are achieved with a very broad frontal lobe (half power beamwidth is 70 degrees in the x-y plane and 150 degrees in y-z plane).
