摘要
设计了一种用于无线传感器网络的结构紧凑的倒F天线,该天线能够满足无线传感器网络尺寸小、价格低廉、功耗低的要求。通过有限元法进行数值仿真和设计,该天线可达到较好的效果。设计制作的天线经测试,在2.45GHz的中心工作频率下,回波损耗为-25dB,带宽为120MHz,满足了IEEE802.15.4协议的要求。
An inverted F antenna is designed for wireless sensor network. It satisfies the requirement of small size, low cost, and low power loss for wireless sensor network. The performance of the antenna can be excellent by numerical simulating and designing using finite element method. The antenna operates at 2.45 GHz with a return loss of -25 dB and a bandwidth of 120MHz, which suits the requirements of the IEEE802.15.4 protocol.
