文中设计一种在贴片上加载开C形缝隙的新型双频微带天线,该天线具有结构简单,体积小,重量轻,制造简单,成本低的优点,适合集成。可以应用在无线局域网802.11b(2.4-2.48GHz)和802.11a(5.150-5.350GHz)的系统中。并且经过实验测得,可以通过改变馈源的位置,实现对天线的高频和低频段的调节。实验测试和仿真结果有很好的效果,适用于无线局域网系统中。
In this paper, we design a new double-frequency microstrip antenna with a C-shaped slit applied on the patch, which has the advantages of simple structure, small size, light weight, simple manufacture and low cost, and is suitable for integration. Can be used in the wireless LAN 802.11b (2.4-2.48GHz) and 802.11a (5.150-5.350GHz) system. And experimentally measured, you can change the position of the feed to achieve high-frequency and low-frequency antenna adjustment. Experimental test and simulation results have good results, suitable for wireless LAN system.
