摘　　要：针对无线设备的发展需求,设计了一种可用于无线局域网和第4代移动通信的多频段天线。该天线采用矩形微带天线结构,通过改变同轴线的馈电位置,并在边缘开一个L形槽,使它在1.94 GHz、2.54 GHz、3.1 GHz和3.4GHz的频段能够有效工作,且拥有一定带宽,满足系统对频率的要求。利用电磁仿真软件,研究了馈电位置、槽的位置及其形状和尺寸对天线性能的影响,实验验证了所设计天线的性能。In order to realize the needs of wireless equipment, a multi-band antenna for wireless local area network and the fourth generation mobile communication systems is designed in this paper. Rectangular microstrip antenna structure is adopted. The position of coaxial feeder is adjusted, and an L-shaped slot is grooved around the edge of radiation patch. The antenna can be worked at 1.94 GHz, 2.5 GHz, 3.1 GHz and 3.4 GHz frequencies with bandwidth enough, and is suitable for frequency requirements above wireless systems. The performances of antenna influenced by the position of coaxial feeder and slot, shape and size of slot are investigated by using electromagnetic simulation software. Experimental results are verified the properties of this design.
