摘要

提出了一种新型的双频锥形波束线极化天线。通过使用两个隔离的对称槽和中央馈线,将产生锥形光束辐射图样。此外,由于其相干结构和准t型馈线,可以实现双频操作。测量结果表明,该天线的下带阻抗带宽为1.8%,上带阻抗带宽为2.6%。本文还将介绍其辐射方向图特征。

Dual-band linearly-polarized slot antenna with conical beam
A novel dual-band linearly polarized antenna with conical beam is proposed in this paper. By using two isolated symmetrical slots and the central feeding line, conical-beam radiation patterns will be generated. In addition, due to its coherent structure and the quasi-T shape feeding line, dualband operations can be attained. The measured result shows that the antenna has the impedance bandwidths of 1.8% for the lower band and 2.6% for the upper band. The radiation pattern characteristic will also be presented.
