摘要
为了实现双频天线的小型化,对平面倒F形天线给出一种改进,在辐射贴片上开一个T形槽,再将它的尾部向内折叠。通过与L形开槽的倒F形天线相比表明:改进后天线的结构更加紧凑,尺寸减小30%以上,且在给定的工作频段具有良好的辐射特性。
In order to make dual-band antenna with more compact size, a planar inverted-F microstrip structure is improved. A T-shaped slot is etched on to radiating patch, which can work on the dual-band, and the end of the patc＇h is folded in. This configuration is more compact; which can reduce the size of antenna more than 30% compared with the L-shaped slot on it. Simulation results show that the antenna has good properties of the radiation at required frequencies
