【摘要】 本文旨在研究人工磁导体表面结构(AMC)在偶极子天线中的应用。将与天线结构相似的AMC单元用作反射板,使得天线的高度降到五分之一波长,并维持天线其他性能不变。经优化,该天线的中心频率为2.2GHz,相对带宽达到34.4%,增益维持在7.97dBi到8.82dBi。更多还原

【Abstract】 The purpose of this paper is to study artificial magnetic conductor(AMC) in the application of the dipole antenna.The AMC unit whose structure is similar with the dipole antenna was used as a reflector,lowered the height of the antenna to one five of a wavelength,and maintain the antenna’s other performance unchanged.The optimized antenna,with a center frequency of 2.2 GHz,a relative bandwidth of 34.4%,and a gain in7.97 dBi-8.82 dBi,is achieved.更多还原
