Abstract


This paper is intended to design a ZigBee wireless network node based on the advanced RISC machines (ARM), so as to facilitate the network usage process. The performance of the new sensor is subject to antenna test and simulation experiment. The HFSS simulation method is adopted, and the antenna size and scanning frequency are optimized through analyzing the research status of ZigBee technology and the working principle of ZigBee protocol stack based on parameters, such as, the return loss and direction of the antenna, which not only increases the accuracy of analysis and but also reduces the reflection coefficient. The experimental results show that when L2 is 14. 9mm, the effect is the best, and Sll is -26.6 dB. Based on the above findings, it is concluded that the integrated antennas on the printed circuit board (PCB) board can reduce the production cost of the antennas; thus, IFA antennas can meet the requirements of ZigBee based wireless sensor network in term of antenna performance.
