Abstract
Two kinds of BMA (Blind Mate A) connector for RFID (Radio Frequency Identification) system, which works at 5.8GHz, is investigated in this paper. The BMA connectors are modeled and simulated in HFSS (High Frequency Structure Simulator). By analyzing the simulation results, three specific steps are adopted to optimize and improve the performance of the RF (Radio Frequency) circuit which is used in the RFID reader antenna port in this paper. At the same time, it chooses a type of BMA RF connector for RFID reader for the actual circuit design. Based on the analysis and optimization of the radio frequency circuit at the antenna port, the first prototype is fabricated and tested in 5.8GHz. The testing result shows that the reflection coefficient is less than -17dB and the VSWR (Voltage Standing Wave Ratio) is less than 1.3, which has a good correspondence with the simulation result in HFSS.
