一种适用于相控阵的超宽带双斜方形天线

内容简介：宽频带是当前天线领域的研究热点之一.目前在相控阵系统中应用最广泛的印制天线有八木天线、领结型天线等.论文提出一种具有超宽带宽的新型传输带-馈线的印制天线,该天线由两个具有不同长度的平行类斜方形偶极子组成.其具有尺寸小,超宽带宽、较宽的波束宽度、增益高及前后比高等优点.通过仿真得到的VSWR和远场辐射方向图分别验证了该天线的特性.在相控阵和宽频带无线通信等领域具有良好的应用前景.

Abstract：Wide band is one of the hot issues in the current researches on antennas. Among the most widely used printed antennas in phased array systems are quasi-Yagi, bow-tie antenna and so on.This paper presented a new microstrip-fed printed antenna design of ultrawide bandwidth. The antenna consisted of two parallel-modified dipoles of different lengths. The regular dipole shape was modified to a quasi-rhombus shape. The proposed antenna provided endfire radiation patterns with small size, wide bandwidth, wide beamwidth, high gain and high front-to-back ratio. Using Ansoft HFSS, the VSWR and far-field radiation characteristics verified the good performance which made it suitable for the phased arrays and wideband wireless communication systems with good prospect.
