- Abstract
- A very small UHF band RFID tag antenna using ceramic material mountable on metallic objects is presented. The proposed tag size is 25x25x3 mm. The impedance of the antenna can be easily matched to the complex conjugate of the tag chip impedance from the size of the shorting plate of the side patch and the size of the feeding loop. The antenna satisfactorily operates on metal plates, so it is applicable in many applications. The proposed design is verified by simulation and measurements which show good agreement.
