摘要

本文提出了一种新型的共线极化全双工天线，该天线在发射端和接收端之间具有很高的隔离性。这种天线依靠印刷在电介质板上的金属贴片进行辐射。为了实现高隔离，使用了带有槽蚀刻的垂直金属壁。通过加载这种结构，两个端口之间的隔离度提高到30dB以上。在我们期望的方向上实现的增益可达5.5dB。这种天线可以应用于许多应用，例如在l波段工作的雷达。由于其辐射特性，该天线也可用于PIN二极管的可重构天线。

A Co-Linearly Polarized Full-duplex Antenna with High isolation for Radar working in L-band

A novel co-linearly polarized full-duplex antenna is presented in this paper, which has a high isolation between the transmitting port and the receiving port. This antenna relies on a metal patch which is printed on a dielectric plate for radiation. To achieve a high isolation, a vertical metal wall with slot etching on it has been used. By loading this structure, the isolation between the two ports has been improved to over 30dB. The realized gain in the direction that we expected can be up to 5.5dB. This antenna can be applied to many applications,such as radars working in L-band. This antenna can also be used to construct reconfigurable antenna with PIN diodes because of its radiation characteristics.
