民用飞机远距离通信天线设计

Design of long distance communication antenna of civil aircraft

摘要:

随着通信技术的不断发展，民用飞机的通信手段也日益更新。目前民用飞机的通信方式主要包括三种，分别为高频（high frequency）通信系统、甚高频（very high frequency）通信系统和卫星通信（satellite communication）系统。天线是通信系统设备的最后一级，其结构与性能的好坏将影响整个无线电系统的通信质量。简要介绍了高频和卫星通信天线的基本辐射原理以及工程实例。高频通信天线采用回线天线的形式，卫星通信天线采用2×6的相控阵天线形式，相控阵天线单元采用缝隙耦合馈电的微带贴片天线形式，最后对通信天线的发展进行了展望。

Abstract:

With the continuous development of communication technology, the communication methods of civil aircraft are also increasingly updated. At present, there are three main methods for civil aircraft, namely high frequency communication system,very high frequency system and satellite communication system. The antenna is the last stage of communication equipment，and its structure and performance will directly affect the communication quality of the entire radio system. This article briefly introduces the basic radiation principles and engineering examples of high-frequency and satellite communication antennas. The high-frequency communication antenna adopts the form of a loop antenna, while the satellite communication antenna adopts the phased array antenna form of 2×6, and the phased array antenna unit adopts the microstrip patch antenna form of gap coupling feeding. Finally the development of communication antenna is prospected.
