近年来,随着对轻量、小尺寸、共形和价格低廉的天线需求的日益增长,使得在微波天线技术中出现了一个新的分支,这就是微带天线。微带天线可以装在火箭、飞机和其它物体上,同时又不致破坏飞行体的空气动力学特性。目前大尺寸印刷电路工艺的进展,对微带无线的发展起着重要的作用。微带天线具有制作简单,性能稳定,结构紧凑坚固,而且可以以任意极化方式工作等优点,从而引起专家们的注意。目前,已制作了各种形式的单阵元微带天线和阵列微带无线,并在着手完善其制作工艺和解决类似天线的一系列重要理论问题。
In recent years, with the increasing demand for lightweight, small size, conformal and inexpensive antennas, a new branch has emerged in microwave antenna technology, which is the microstrip antenna. Microstrip antennas can be mounted on rockets, aircraft and other objects without damaging the aerodynamics of the flying body. The current progress of large-size printed circuit technology, the development of microstrip wireless plays an important role. Microstrip antenna has the advantages of simple manufacture, stable performance, compact structure and robustness, and can work in any polarization mode, which draw the attention of experts. At present, various forms of single-element microstrip antennas and array microstrip wireless lines have been made and a series of important theoretical issues are under way to improve their manufacturing process and to solve similar antennas.
