摘要

为了提高宽带带宽，本文提出了一种带槽加载叠加贴片和缺陷接地面结构的宽带截断矩形微带天线。通过在地平面插入槽，使叠置截断矩形微带天线的带宽提高了一倍。在2.72 ~ 5.26 GHz范围内，在地结构中增加槽前的带宽为29.7%，而在地平面中增加槽后的带宽为63.65%。辐射方向图在两个E&H平面上都有可接受的响应。天线设计在FR4玻璃环氧基板上，采用同轴馈电技术。给出了天线的设计细节和仿真结果。

Bandwidth Enhancement for Truncated Rectangular Microstrip Antenna Using Stacked Patches and Defected Ground Structure

Wide band truncated rectangular micro strip antenna with slot loaded stacked patches and defected ground plane structure is presented in this paper to increase the bandwidth. By inserting slot in the ground plane the bandwidth of the stacked truncated rectangular micro strip antenna is improve by twice. The bandwidth before adding the slot in the ground structure was 29.7% whereas after adding the slot in the ground plane of a stacked truncated rectangular micro strip antenna it increases up to 63.65% ranging from 2.72 to 5.26 GHz. The radiation pattern has acceptable response at both E&H plane. The antenna is design at FR4 glass epoxy substrate fed by a coaxial feeding technique. Detail of the proposed antenna and the simulated results are presented.
