提出了一种新型的紧凑型圆极化天线,它可以很容易地制造和嵌入到RFID阅读器中。通过引入交叉分支实现了天线的圆极化特性。改进的曲折线结构使天线具有紧凑性。制作了样机并进行了测量。结果表明,该圆极化天线结构紧凑,可覆盖920 ~ 925 MHz的中国RFID工作频段,适合RFID读写器手持终端应用。
A novel compact and circular polarized antenna is proposed which can be easily fabricated and embedded into RFID readers. Circular polarization characteristic of the proposed antenna is achieved by introducing a crossed branch. The modified meandering line structure gives the antenna compactness characteristic. A prototype is fabricated and measured. The results show that this circular polarized antenna with compact dimension can cover the Chinese RFID operating band from 920 MHz to 925 MHz, which make's the antenna suitable for handheld terminal application of RFID readers.
