提出了一种用于移动超高频射频识别的新型极化分集天线，该天线采用一对平行偶极子。天线由一对垂直放置在馈电网络上的平行偶极子组成。与半波长传统偶极天线相比，该天线的整体尺寸小于四分之一波长。平行偶极子下的馈电网络紧凑简单，可以产生垂直线极化和水平线极化。采用本文提出的极化分集天线可以提高RFID标签的检测能力，从而提供稳定可靠的RFID服务。天线峰值增益为2.05 dBi，两个输入端口之间的隔离小于-18dB。给出了天线的设计细节，并给出了测量和仿真结果来验证所提出的思想。
A novel compact polarization diversity antenna using a pair of parallel dipoles for mobile UHF radio frequency identification (RFID) is presented. The antenna is composed of a pair of parallel dipoles orthogonally placed on the feeding network. Compare to half wavelength conventional dipole antenna, the overall size of this antenna is less than quarter wavelength. With the compact and simple feeding network below the parallel dipoles, the proposed antenna can generate vertical linear polarization and horizontal linear polarization. The use of the proposed polarization diversity antenna may lead to the higher detection of capability of RFID tags, thus providing the stable and reliable RFID services. Antenna peak gain is 2.05 dBi, and isolation between the two input ports is less than -18dB. Details of the antenna design are shown, and the measurement and simulation results are also provided to validate the proposed idea.
