摘要
本文提出了一种适用于医疗应用的小型、低姿态、便携式RFID阅读器，并对其天线进行了设计、实现和测试。具体而言，提出了一种与介质控制塑料支架共形的圆极化超高频RFID阅读器天线。辐射元件是通过一个由四个倒f单极子组成的圆形阵列来实现的，其中阵列元件通过微带馈电网络以90度相位偏移(顺序旋转馈电技术)进行激励。为了实现友好的原型，天线结构被认为是在粘接铜上成型的，而电介质支撑则是用聚乳酸(PLA) 3d打印的，由于其有趣的低损耗特性，选择得恰到好处。非常紧凑的天线(60mm x 60mm x 6.5mm)，适用于所需的便携式阅读器，在反射系数，端口隔离和辐射模式方面具有特点。
Circularly Polarized Antenna in 3D Printing Technology to Feed a Wearable Fully-Integrated WiFi-RFID Reader for Biomedical Applications
In this work, a compact, low-profile, portable RFID reader suitable for medical applications has been proposed and its antenna designed, realized and tested. Specifically, a circularly polarized UHF RFID reader antenna conformal to a dielectrically controlled plastic support is proposed. The radiating element has been realized through a circular array of four inverted-F monopoles, where the array elements are excited with a 90-degree phase offset (sequential rotation feeding technique) through a microstrip feeding network. To allow for a friendly prototype realization, the antenna structure is thought to be shaped on adhesive copper and the dielectric support to be 3D-printed in Poly-Lactic Acid (PLA), opportunely selected due to interesting low losses properties. The very compact antenna (60mm x 60mm x 6.5mm), suitable for the desired portable Reader, has been characterized in terms of reflection coefficient, port isolation and radiation patterns.
