前言目前,有些应用要求使用在 Ka波段(35—40GHz)工作的体积小(口径为4到5时)、旁瓣低(-30db)的天线。另外,一般还要求同时产生右旋和左旋极化并能在比较大的功率(200瓦,连续波)下工作。本文介绍了满足这些要求的两种典型天线及其性能的实验结果。
Foreword At present, some applications require the use of small-sized (4 to 5-caliber), sidelobes (-30db) antennas that operate in the Ka-band (35-40GHz). In addition, it is also generally required to produce dextrorotatory and left-handed polarizations simultaneously and to operate at relatively high power (200 watts, continuous wave). This article presents the experimental results of two typical antennas that meet these requirements and their performance.
