摘要
针对当前无线电通信中短波频段所面临的传输效率低、覆盖范围有限及抗干扰能力差等挑战,深入探讨中短波宽带天线及其匹配网络的设计与优化策略,并结合双线传输线和变压器技术设计一种新型的中短波宽带天线。该天线具有结构简单、频带宽及抗干扰能力强等优点,能够有效提高无线电通信的传输效率。此外,详细研究了天线匹配网络,并提出一种集中电阻加载设计方法。精确调控加载元件的位置和阻值,可以有效增强天线的匹配性能,进一步提高无线电通信的传输效率。
In response to the challenges faced by low transmission efficiency,limited coverage range,and poor anti-interference ability in the short wave frequency band of current wireless communication,this paper deeply explores the design and optimization strategies of medium and short wave broadband antennas and their matching networks,and designs a new type of medium and short wave broadband antenna combining dual line transmission line and transformer technology.This antenna has the advantages of simple structure,wide frequency band,and strong anti-interference ability,which can effectively improve the transmission efficiency of wireless communication.In addition,a detailed study was conducted on the antenna matching network,and a centralized resistor loading design method was proposed.By precisely adjusting the position and resistance of the loading element,the matching performance of the antenna can be effectively enhanced,further improving the transmission efficiency of wireless communication.
