微带缝隙天线设计
摘要
通信系统的发展带来了天线行业的勃勃生机,在众多的天线类型中微带天线已成为当前研究的前沿之
一,很具有研究前景与实用意义。特别是微带缝隙天线,以其重量轻、剖面薄、平面结构且易与载体共形,馈电网络可与天线结构一起制成等优点已经引起天线工作者的广泛关注。本文简要介绍了微带天线和微带缝隙天线的分类、分析方法、主要参数,然后提出了一种三角形缝隙微带天线。在介质基板的一面一个三角形缝隙,另一面采用一个等腰三角形微带线进行馈电。通过仿真给出了天线的s参数,VSWR和方向图。该天线的阻抗带宽达到了120% ,覆盖了2.6—11.7GHZ的频率范围,增益值达到了5.8dB。

Microstrip Slot Antenna Design
Abstract数字调节器
The development of Communication System has brought exuberant vital force of The Antenna Industry. In lots kinds of antenna, the Microstrip antenna has already been one of the most foreland research, with foreground and practical significance. Especially, the Microstrip slot antenna has attract attention of antenna operators with it’s characters: light, thin section, plane structure, conform with carrier easy, feeding network can be made with the antenna structure. This thesis has given a brief introduce on the classes, analysis methods and the main parameters of Microstrip antenna and
Microstrip slot antenna, then has proposed a kind of triangular-shape slot Microstrip antenna. A triangular-shape slot exists on a side of the substrate, and it can feed with an equilateral triangular-patch on the other side. Parameter S, VSWR and the Direction Plot of the antenna are given by the simulation. The impedance bandwidths of the proposed antenna approach 120%, covering 2.6—11.7GHZ, and the plus get to 5.8dB.
Keywords: Mrcrostrip antenna, Microstrip slot antenna, triangular-shape slot Microstrip antenna.
