一、引言毫米波段由于其突出的优点已被广泛应用于通讯、雷达、制导、遥感等系统。毫米波天线可以分为两大类,一类是传统结构的天线,另一类是基于新概念设计的天线。第一类天线如反射面、透镜、喇叭天线等。这一类天线的设计,毫米波与微波波段区别不大。第二类天线则包含了近来发展起来的一些新概念。这些天线多半是根据毫米波段的别点发展起来的,而且还在不断研究中。这一类天线包括微带夭线,由开波导或普通波导激励的行波天线,类微带集成夫线等。本文着重对第二类即新型毫米波天线作一综述。由子这一类天线型式繁多,这里只能举一些典型的或常用的线极化天线。
I. INTRODUCTION The millimeter wave band has been widely used in the fields of communication, radar, guidance and remote sensing because of its outstanding advantages. Millimeter-wave antennas can be divided into two categories, one is the traditional structure of the antenna, the other is based on the new concept of design of the antenna. The first type of antenna such as reflector, lens, horn antenna. This kind of antenna design, millimeter wave and microwave band is not very different. The second type of antenna contains some new concepts that have been developed recently. Most of these antennas are based on something other than millimeter-wave development, and are still under continuous research. This type of antenna, including microstrip antenna, by the waveguide or ordinary waveguide-inspired traveling wave antenna, such as micro-class integrated husband and wife. This article focuses on the second category that is a new type of millimeter-wave antenna for a review. Sub-types of this type of antenna, here can only cite some typical or commonly used linear polarization antenna.
