摘要
微带贴片天线是一种低材料、体积小、易于制作的天线。为了实现天线的多频带特性,在微带贴片天线中引入了sierpinski模型结构。分形结构是在一个递归的过程中产生的,它们可以在有限的空间产生很长或很宽的表面积,因此,分形结构可以使宽带天线在小型化的同时又能保持和大天线相似的辐射模式和输入阻抗特性。这种sierpinski分形结构的微带天线可以用在WLAN,BLUETOOTH和WIMAX中。本文详细研究了sierpinski分形结构的迭代设计以及馈带线的馈点位置。
A microstrip patch antenna is a low profile, small size and can be easily made, In order to get the multibands, sierpinski geometry is introduced on the microstrip patch antennas. The fractal structures are generated by a recursive process,they can produce a very length or a wide surface area in a limited space.Consequently, fractal structures can give rise to miniaturized wideband antennas having radiation patterns and input impedance characteristics similar to the larger antennas. The microstrip sierpinski antenna can be used in the WLAN,Bluetooth and WiMAX.In this paper,we researched the iteration design of sierpinski geometry and the location of feed point, analyzed the proper feed point as to this sort of microstrip antenna.
