摘　　要：随着现代应急系统的逐渐完善与通信技术的飞速发展,应急单兵通信装备中的天线结构正朝着小型化和可共形化的方向发展,通信频段朝着多频段和宽带化的方向发展。天线作为无线通信系统中重要的无线收发器件,其通信性能对无线通信系统影响至关重要。本文通过高频仿真软件HFSS研究设计了一款可用于应急救援的双枝节结构共面波导织物天线,并通过射频基础公式计算出谐振频点,以简单的双枝杈结构作为辐射体,接地面为倒三角形,使整体表面结构能与臂章共形,达到可穿戴的目的。其覆盖的频段为1.5~2.09GHz和2.54~3.09GHz,增益为0.1~2.9 dBi,效率为53%~60%。该天线可用于2G、FDD、F频段、5G中2.6 GHz频段和卫星接收频段。With the gradual improvement of modern emergency systems and the rapid development of communication technology,the antenna structure in emergency individual communication equipment is developing towards miniaturization and conformability,and the communication frequency band is developing towards multi band and broadband.As an important wireless transceiver in wireless communication systems,the communication performance of antennas is crucial to the wireless communication system.This article designs a coplanar waveguide fabric antenna with a double branch structure that can be used for emergency rescue through the study of RF antennas.And the resonant frequency point is calculated using the RF basic formula,using a simple double branch structure as the radiator and an inverted triangle as the ground plane,so that the overall surface structure can conform to the armband,achieving the goal of wearability.It covers frequency bands of 1.5~2.09 GHz and 2.54~3.09 GHz,with a gain of 0.1~2.9 dBi and an effi ciency of 53%~60%.The antenna can be used in 2G,FDD,F-band,2.6 GHz in 5G and satellite reception frequency bands.
