L型探针馈电的微带天线仿真设计L 型探针垂直部分及水平部分和贴片之间产生感抗和容抗，两者相互作用产生谐振，使天线频带拓宽或者呈现多频带。这使得L型探针馈电广泛应用于现代移动通信系统中。本文介绍了微带天线的辐射原理及微波射频段电磁波的基本理论及L型探针馈电的微带L型探针馈电的微带design and Simulation of antenna with L-shaped probe feed Absract In recent years,with the increasing number of mobile communication system,communication equipment developed towards miniaturization direction constantly,and the antenna size,high integration and frequency requirements are also becoming more and more important.Light weight, with low profile,low cost and ease of integration has got widespread attention by all of us.The major limitations of microstrip antenna now is the bandwidth of the antenna. After decades of development,a lot of research scholars proposed method to expand the bandwidth of the microstrip patch antenna,which adopts the L-shaped probe feed get a lot of attention. Because vertical section and horizontal section of L-shaped probe create inductive reactance and capacitive reactance,and both of them interact to produce resonance, this makes the antenna has wide bandwidth or multiple frequency bands. This makes L-shaped probe feed is widely used in modern mobile communications system. This paper introduces the radiation principle of microstrip antenna and microwave radio frequency section of the basic theory of electromagnetic wave transmission and the antenna with L-shaped probe feed. Based on the basic theory of microstrip antenna analysis and numerical calculation design a microstrip antenna meet the design need,and analysis the effect of the size horizontal and vertical section of L-shaped probe on the antenna bandwidth with the aid of with simulation software HFSS.In the final,it designs a microstrip antenna with L-shaped probe feed which the transmission signal frequency band in 3.2~4.4 GHz.
