引言 微带天线由于具有一系列独特的优点,正在受到人们越来越多的重视,可以预计,在不远的将来,微带天线将在很广泛的应用场合取代人们已应用了多年的一大类天线。 微带天线固有的一个重要特性——多频特性,即一个微带天线可以在离散的多个频率点上工作的特性,至今尚未被人们所充分认识、研究和利用。本文初步研究了微带天线的多频特性(对VSWR而言),包括多频的观测、实验和理论分析。
Introduction Microstrip antennas are gaining more and more attention due to a series of unique advantages. It can be predicted that in the near future, microstrip antennas will replace the large ones that have been used for many years in a very wide range of applications Antenna. One of the most important characteristics of microstrip antennas, that is, the multi-frequency characteristic that a microstrip antenna can work on a plurality of discrete frequency points has not been fully recognized, studied and utilized by people. In this paper, the multi-frequency characteristics of microstrip antennas (for VSWR) are studied preliminarily, including multi-frequency observation, experiment and theoretical analysis.
