摘要

缺陷接地结构(DGS)的概念是为了改善许多微波器件的特性而发展起来的。在微带贴片天线中，采用缺陷接地结构(DGS)实现了微带贴片天线的小型化，在不改变原微带贴片天线尺寸的情况下，将谐振频率从初始值10 GHz移动到最终值3.5 GHz。该天线设计在介电常数为4.4、厚度为1.6 mm的FR-4衬底上，尺寸为27 × 30 mm2。采用CST技术对天线进行了设计、优化和小型化。

A new design of a miniature microstrip patch antenna using Defected Ground Structure DGS

The concept of Defected Ground Structures (DGS) has been developed to improve the characteristics of many microwave devices. For this purpose the DGS is also used in the microstrip antenna for some advantages such as antenna size reduction, mutual coupling reduction in antenna arrays etc… In this paper the defected ground structure (DGS) has been employed to miniaturize a microstrip patch antenna and to shift the resonance frequency from an initial value of 10 GHz to a final value at 3.5 GHz, without any change in the dimensions of the original microstrip patch antenna. This antenna is designed on a FR-4 substrate with dielectric constant 4.4 and thickness 1.6 mm and its size is 27 × 30 mm2. The antenna is designed, optimized, and miniaturized by using CST MW.
