Abstract


The Internet of Things (IOT) is an emerging technology, which contains sensor network, radio frequency identification (RFID) and traditional Internet. Along with the violent development of the industry of IOT, as an important part of the Internet of Things, the IOT antenna will receive more and more attention and research. Since antenna’s performance affects the performance of the whole system, it is necessary to design the antennas with high performance to meet various applications, also in order to better support the industry’s development.This thesis, starting in knowledge related the Internet of Things, in the analysis of advantages of the antenna array and the microstrip antenna, establishes the simulation models of microstrip antenna array. According to the models, two real antennas are produced, and the measured data compares with the simulation results based on HFSS, which verifies the feasibility of models.The contents of study in the thesis are given as follows:1. This thesis outlines the knowledge relevant the Internet of Things and the research situation at home and abroad about IOT antenna. Secondly, the basic theory on antenna and some antenna parameters are introduced briefly.2. The contents of antenna array are discussed and the principle of pattern multiplication is elaborated, which focuses on the analysis of the changes of array factor with various factors by Matlab.3. The thesis analyzes the characteristics and advantages and disadvantages of microstrip antenna, and gives a clear design process on microstrip antenna.4. Based on the results of theoretical analysis, two models of the microstrip array antenna models with high gain are established. Then according to the models, two real antennas are made and measured. At last, according to the comparison the measured data with the simulation results based on HFSS, the theoretical models are verified.
