Abstract
Modern technology, wireless communication technology as an important technology of the times change, the development trend of the more rapid, and for all types of intelligent mobile communication terminal data transmission bandwidth and speed of the demand is also growing, I believe in the near future 5G communication technology applications will enter the lives of ordinary people, change people's way of life, so that people have a more convenient future. As far as the whole communication system is concerned, the antenna is one of the most important and essential parts, which is closely related to the merits of the performance of the communication system. Therefore, in this context, in order to meet the future needs of wireless communications, in this issue will be on the millimeter-wave antenna to study.
In this paper, based on the research of Alford square ring antenna, the design of highly miniaturized planar microstrip antenna in 28 GHz frequency band is based on the double "Z" type microstrip structure to meet the requirements of the working frequency band and the communication environment. And other performance parameters, and then through the meandering and model scale and other technologies to optimize the design, and ultimately achieve miniaturization, ultra-wideband and high-speed transmission characteristics of the antenna design requirements and use in the future communications mobile terminal, which is The significance of this research.
Key words: Wireless communication; microstrip antenna; miniaturization; meandering and scale technology
