Abstract

Increasing the read distance of a Radio Frequency Identification (RFID) system is a challenging problem. A new Ultra High Frequency (UHF) RFID reader antenna has been designed to increase the coverage area. A Quadrifilar Helix Antenna (QFHA) with a shaped radiation pattern has been simulated to verify its performance. The shaped radiation pattern of the QFHA will increase read distance when the reader antenna is centered above a coverage area.

一种异形波束RFID阅读器天线的设计

增加射频识别(RFID)系统的读取距离是一个具有挑战性的问题。设计了一种新的超高频(UHF) RFID读取器天线，以增加覆盖面积。对一种具有异形辐射方向图的四线螺旋天线(QFHA)进行了仿真，验证了其性能。当读取器天线位于覆盖区域的中心上方时，QFHA的形状辐射方向图将增加读取距离。
