摘要

提出了一种可用于物联网传感器的新型平衡式多频段标签天线的设计概念。该天线具有完全对称的结构

易于直接与差分驱动的射频前端电路集成在一起;通过大量的模拟计算

对天线的表面电流分布、方向图、阻抗特性、增益等指标进行了详细的数值分析

确定了天线的基本工作原理。计算与初步实验结果表明

该天线能完全覆盖2.4～2.5GHz/5.1～12GHz等射频识别与短程无线接入系统的工作频段

且具有较小的体积与中等的增益

因此有望用作物联网无线传感器中的标签天线。

Abstract

Design concept of a novel balanced multi-band tag antenna for Internet of things sensors applications was proposed.The antenna has a symmetrical structure so that it can be easily and directly integrated with differential driving RF front ends.The antenna’s surface current distribution

radiation patterns

impedance matching characteristics and gain

were numerically studied by using computer simulations

and the operating principle of the antenna was determined.Based on the numerically and basic experimental results

it is concluded that the antenna has a compact size and moderate gain

and can cover the bands of 2.4～2.5GHz/5.1～12GHz

which are for RFID and short-range wireless access applications.Thus the antenna can be used as tag antenna for wireless sensors in Internet of things.
