Studies on design methods on multifunctional, electrically small andlow-profile antenna for small wireless terminals

在本项目中，作者所在的课题组旨在建立适用于移动的手机的小型天线的设计方法。主要包括电小天线、带背导体的低剖面天线、宽带天线、波束可调天线、圆极化细长天线等多功能天线，具体包括：1.采用人工接地结构的宽带圆极化贴片天线，2.宽带圆极化波导天线，3.波束可调圆极化天线，4.采用电容馈电结构的电小天线，5.低相关MIMO天线

In this project, the author’s group has aimed to establish thedesign way for small antennas for mobile handsets. Mainly, they are electrically smallantennas, low-profile antennas with a back conductor, multifunctional antennas such asbroadband antennas, beam steerable antennas and circularly polarized slender antenna.Followings are details; 1: Broadband circularly polarized patch antenna using artificialground structure, 2:broadband circularly polarized waveguide antenna, 3:Beam-steerable circularly polarized antenna, 4:electrically small antennas using acapacitive feed structure and 5: MIMO antenna with low-correlation
