微带贴片天线（MPA）的基本几何结构由印刷在接地基板上的金属贴片组成。三种常用的馈电方法是同轴馈电、带状线馈电和孔径耦合馈电。贴片天线的想法最早是在20世纪50年代初提出的，但直到20世纪70年代末，这种类型的天线才引起了天线界的严重关注。微带贴片天线提供了低剖面、适形于成形表面、易于制造以及与集成电路技术兼容的优点，但是基本几何形状受到窄带宽的影响。在过去的三十年里，人们对这种天线的性能进行了广泛的研究，MPA在军事和商业领域都有许多应用。本文首先简要介绍了MPA的建模技术和基本特征。宽带的方法，双和多波段的设计，尺寸减小技术，并设计圆偏振。本文件最后提出了一些结论性意见。
The basic geometry of a microstrip patch antenna (MPA) consists of a metallic patch printed on a grounded substrate. Three commonly used feeding methods are coaxial feed, stripline feed, and aperture-coupled feed. The patch antenna idea was first proposed in the early 1950s, but it was not until the late 1970s that this type of antenna attracted serious attention of the antenna community. The microstrip patch antenna offers the advantages of low profile, conformability to a shaped surface, ease of fabrication, and compatibility with integrated circuit technology, but the basic geometry suffers from narrow bandwidth. In the last three decades, extensive studies have been devoted to improve the performance of this antenna and the MPA has found numerous applications in both the military and the commercial sectors. This article begins with a brief description of the modeling techniques and basic characteristics of the MPA. Methods of broadbanding, dual and multiband designs, size-reduction techniques, and design for circular polarization are then reviewed. The paper ends with some concluding remarks.
