摘要:

针对天线的多频问题,提出一种新型的三频段平面倒F天线(PIFA天线),该结构采用在辐射贴片上开U形槽和∏形槽来实现。通过HFSS13.0对天线模型进行仿真分析,使得天线最终工作于GSM(890~960 MHz)、DCS(1 710~1 880 MHz)和ISM2 400 MHz(2 400~2 484 MHz)3个频段。仿真结果表明,3个频段的相对带宽分别为10%、6%和11%,能满足通信要求。此外,天线整体辐射性能良好,且结构简单。

Abstract:

Aiming at the problem of multi frequency antenna,a novel planar inverted F antenna (PIFA antenna) is proposed by using the U shaped groove and groove on the radiation patch.Through the simulation analysis of the antenna model by HFSS13.0,the antenna is made up of the three frequency bands of GSM (890~960 MHz),DCS (1 710~1 880 MHz) and ISM2 400 MHz (2 400~2 484 MHz).The results show that the relative bandwidths of the three frequency bands are 10%,6% and 11%,respectively,which meet the requirements of communication.The antenna has good overall radiation performance and simple structure.
