摘要

摘要: 超宽带天线和可重构天线是当今天线领域研究的热点。将可重构天线技术应用到超宽带天线设计中,讨论了频率可重构超宽带天线的设计思路。以印刷单极子椭圆天线为原型,给出了两个可重构天线的具体结构,并对天线进行了可重构带阻设计,避免与相关频段之间的干扰。仿真结果表明:重构后天线Ⅱ的低频获得了扩展,其相对尺寸的长和宽分别减小到最大工作波长的0.116倍和0.087倍,工作频段为0.174~10.9GHz,可重构阻带为5.1~5.95GHz,带宽比可高达62:1.

Abstract: Nowadays, UWB antennas and reconfigurable antennas are both hot research fields.In this paper, the technology of reconfigurable antenna is applied to ultra-wideband antennas, and the basic design idea of frequency reconfigurable UWB antenna is discussed.Based on the elliptical planar monopole antenna, two reconfigurable UWB antennas are presented.In order to avoid interference with other communication band, an antenna is designed with a reconfigurable bandnotch. The simulation results of antenna Ⅱ show that after reconfiguration, the LF band is extended.Simultaneously, the length and width of relative size are reduced to 0.116 and 0.087 times of the maximum operating wavelength.The antenna Ⅱ operates at 0.174~10.9 GHz, and the reconfigurable notched band is 5.1~5.95 GHz.Moreover, the bandwidth ratio is 62:1.
