摘要

物联网(IoT)基站应用的印刷电路板(PCB)天线的实现是天线尺寸、形状、位置和板/地布局的协同设计。本文研究了一种典型的结合偶极子结构的PCB天线的辐射特性。提出了一种圆极化差分馈电天线，并进行了实验验证。利用PCB天线的辐射特性和偶极子元件的工作原理，对差分馈电信号可以实现CP辐射。所提出的天线在效率和带宽方面具有良好的辐射性能。

Circularly Polarized Dipole-like Antennas for Differentially-Fed IoT Applications

The implementation of Printed Circuit Board (PCB) antennas for the Internet of Thing (IoT) base station application is a co-design of the antenna size, shape, position, and board/ground layout. This paper investigates the radiation features of a typical PCB antenna combined with a dipole-type structure. A circularly polarized (CP) antenna for differential feeding is proposed and experimentally verified. By taking the advantage of the PCB antenna radiation and working principle of the dipole element, it is shown that CP radiation could be achieved for differential-fed signals. The proposed antennas demonstrate good radiation performance in terms of efficiency and bandwidth.
