摘要
设计具有适当的信号接收和发射能力的射频识别标签是一项具有挑战性的任务。为此，提出了多种天线。本文结合单极天线和微带天线的设计，提出了一种这样的设计方案。工作频率范围设计为2.2-2.6 GHz和5.3-6.8 GHz，适合RFID工作频段。单极天线制作成“F”形。FR-4介电材料已使用38 x 45 x 1.6 mm3尺寸。利用ANSYS HFSS软件对回波损耗、驻波比、指向性和增益参数进行了分析。“F”模式的结构使天线适用于RFID应用。
Directivity Analysis for Dual-Band Monopole Antenna for RFID Applications
Design of radio-frequency identification tag with proper signal receiving and transmitting capability is now a challenging task. For that many kinds of antennas are proposed. This paper provides one such kind of design, incorporating the design of monopole antenna and micro-strip antenna. The operating frequency ranges are designed for 2.2–2.6 GHz and 5.3–6.8 GHz, which is suitable for RFID operation bands. Monopole antenna is fabricated in ‘F’ shape. FR-4 dielectric material has been used with 38 x 45 x 1.6 mm3 size. Return loss, VSWR, directivity and gain parameters are analysed using ANSYS HFSS software. The structure of ‘F’ pattern makes the antenna suitable for RFID applications.
