摘要
近几年,随着技术的发展,人们对调频发射系统性能提出的要求越来越高,要想使该系统的作用得到最大限度发挥,关键是要了解系统现存不足,制定并实施相应的升级改造方案。文章便以此为背景,首先介绍了什么是天线极化,以及单一极化、混合极化天线的特征,其次分析了将混合极化天线用于调频发射系统的实际案例,最后结合实际案例,深入剖析了混合极化天线所具有的性能优势。希望能够给人以启发,为日后建设、升级无线发射系统等工作提供有益参考。
in recent years,with the development of technology,people put forward higher and higher requirements for the performance of FM transmitting system,formulate and implement the corresponding upgrading and transformation plan.Based on this background,this paper first introduces what is antenna polarization,and the characteristics of single-polarization and mixedpolarization antenna,and then analyzes the practical case of using the mixed-polarization antenna in FM transmitting system,finally,the advantages of hybrid polarization antenna are analyzed in detail with a practical case.Hope to inspire people,for the future construction,upgrading of wireless transmission systems and other work to provide useful reference.
