摘要

对于一些超宽带应用(短距离雷达,医学成像),已经证明使用支持双极化的天线可以提高它们的精度。然而,经典的超宽带双极化天线的尺寸使其难以集成到小型设备中。随着尺寸变得至关重要,小型化技术之前已经在超宽带环境下进行了研究。在本文中,我们的目标是提供一种具有双极化辐射方向图的电小超宽带天线。研究了一种双极化正弦天线的平面小型化技术。在不影响带宽或辐射性能的情况下,尺寸减小了32%。

Miniaturization of an UWB Dual-Polarized Antenna
For some UWB applications (short range radars, medical imaging), it has been shown that the use of an antenna that supports a dual-polarization can enhance their accuracy. However, the size of classic UWB dual-polarized antennas makes their integration into small devices difficult. As size became crucial, miniaturization techniques have been previously investigated in an UWB context. In this paper, we aim to provide an electrically-small UWB antenna with a dual-polarized radiation pattern. A planar miniaturization technique has been investigated on a dual-polarized sinuous antenna. A size reduction of 32% has been achieved without compromising on either bandwidth or radiation performances.
