ABSTRACT

A novel dual-band antenna of RFID reader is proposed. The antenna adopted a single layer substrate of FR4 medium. A four-pointed star was cut in the middle of the radiation patch, and a half four-pointed star was slotted on each side. Then the size reduction and dual-band coverage were realized. Through simulation and analysis, the geometric size of the antenna is 68mm×68mm×1.6mm, the operating band are 0.91GHz~0.935GHz and 2.40GHz~2.51MHz, and the relative impedance bandwidth are 2.72% and 4.49% respectively. Also, the antenna has good radiation characteristics in the operating band. The antenna can meet the requirements of the handheld RFID reader antenna with low cost and minimization.
