Ultra-Wideband Antenna for RFID Underground Oil Industry Application

Radio Frequency Identification (RFID) systems, to its recent technologies. A study is presented to implement ultra-wideband (UWB) Vivaldi antenna for RFID underground oil industry application. And typically we look into low frequency operation for good penetration but we keep the small size of the antenna. The proposed antenna has overall size 82x92x1.6mm. Simulation analysis is performed under CST Microwave Studio environment. The performance of the antenna is tested in three background materials: air, oil and water, with results illustrate the superiority of this structure UWB-RFID oil industry application. Simulated and measured reflection parameters of the proposed structure are evaluated. An earth model is used to investigate the proposed antenna an oil exploration. Results are presented, showing the performance of the antenna with and without model an earth model and this antenna can be used at UWB RFID application.
