PCB 天线的分析及应用设计

内容简介：本文首先分析常见的几种 PCB 天线设计的优缺点，然后结合一款设备发射频率为430MHz，尺寸非常紧凑(28.1mm×5.5mm)的产品，分别按照几种常用的 PCB 设计进行了讨论，最后重点研究了 PCB 螺旋天线的设计方案。实验测得PCB 螺旋天线的信号强度和辐射距离完全符合设计要求，各项功能运行良好。

Abstract： This paper analyzes the strengths and weaknesses of several common PCB antenna designs,and then proposes several commonly used PCB designs for a device with emitting frequency of 430MHz and very compact size of 28.1mm × 35.5mm respectively.According to discussion above,the PCB helical antenna design are finally focused.Experiments show that PCB helical antenna fulfills compliance with the design requirements in aspects of signal strength and radiation distance,and the various functions work well.
