随着近代宇航及高速飞行器的发展,为了克服空气阻力及特殊环境因素影响,近年来,国外广泛开展了新型微带天线的研究。微带天线体积小,结构简单可靠。便于加工,成本较低。微带天线在国外宇航通信方面已获得应用。它的不足之处是工作频带较窄,应用中受到一定限制。本文论述几种微带天线的工作原理和设计方法。并给出一些电参数测量结果。一、微带辐射元工作原理图1为方形辐射元,由导电薄片及厚度为零点几
With the development of modern aerospace and high-speed aircraft, in order to overcome the influence of air resistance and special environmental factors, a new type of microstrip antenna has been widely researched abroad in recent years. Microstrip antenna small size, simple and reliable structure. Easy to process, low cost. Microstrip antennas have been used in foreign aerospace communications. Its disadvantage is the narrow working frequency, the application is subject to certain restrictions. This article discusses several microstrip antennas working principle and design method. And gives some electrical parameters measurement results. First, the working principle of the microstrip radiating element Figure 1 is a square radiating element, the conductive sheet and the thickness of zero
