卫星通信和卫星直播电视(DBS)的发展,促进了天线技术的发展。在常规的接收天线中,主要是应用反射面(盘)天线.如标准抛物面天线、双反射面天线及为了解决效率和旁瓣矛盾而发展起来的偏置反射面天线等。这些天线对安装环境要求高,由于狂风和雨雪等环境因素,常常会损坏天线或引起变形,从而导致天线性能的下降。近年来,国际上都在注意平板型天线的研究,并取得了一定的进展。本文介绍的是一种在廉价的泡沫塑料上制作的三明治结构形式的微带平板天线,其波束方向是倾斜的(在俯仰方向偏离天线视轴24°)。加上一些简单的方
The development of satellite communications and satellite live television (DBS) has contributed to the development of antenna technology. In the conventional receiving antenna, the main application of the reflective surface (dish) antenna, such as the standard parabolic antenna, dual-reflector antenna and in order to solve the efficiency and sidelobe contradictions and the development of the bias reflector antenna. These antennas have high requirements on the installation environment. Due to environmental factors such as wind and rain and snow, they often damage the antenna or cause deformation, resulting in the degradation of the antenna performance. In recent years, the international community has paid attention to the study of flat-type antennas and has made some progress. This article presents a microstrip patch antenna in the form of a sandwich made of inexpensive foam that has a beam direction that is tilted (24 ° off the boresight of the antenna in the pitch direction). Add some simple side
