摘　　要：为了降低节点功耗和在发射功率不变的前提下增大其通信距离,在节点设计原则基础上,提出一系列解决方案来减少节点电路板不必要的能量损耗;选用巴伦匹配的传输线使得同等发射功率下节点通信距离增大。设计实现了一种基于处理器ATmega128L和射频芯片CC2420的低功耗、低成本和小型化的无线传感器网络节点。对该节点和MICAz节点进行性能测试实验,结果表明,该节点较MICAz节点功耗小、同等发射功率下通信距离远。In order to consume less energy and increase communication distance with the same radio power, based on the principle of wireless sensor networks （WSNs） node design, some solutions were proposed to reduce energy loss; A Balun was implemented in combination with transmission lines to increase the communication distance with the same radio power. A novel low power, low cost and small scale node was presented by the use of ATmega128L and RF IC CC2420. The experiment results show that the novel node consumes less energy and has a longer communication distance compared with the generally used MICAz.
