Abstract
This paper proposes a 2-D fully polarized Van Atta array, which consists of four tri-polarized antenna elements. The tri-polarized antenna element comprises a monopole antenna and a low-profile microstrip antenna that widens the beam by folding four electric walls. This configuration enables the Van Atta arrays to receive and transmit arbitrarily polarized incident waves over a wider range. The measurement results indicate that the proposed Van Atta array exhibits a -5 dB radar cross-section (RCS) greater than 95° when TE-polarized waves are incident and greater than 134° when TM-polarized waves are incident, significantly surpassing the 2-D dual-polarized array.
本文提出了一种二维全极化 Van Atta 阵列,它由四个三极化天线元件组成。三极化天线元件包括一个单极天线和一个扁平微带天线,后者通过折叠四个电墙来拓宽波束。这种配置使范阿塔阵列能够在更大范围内接收和发射任意极化入射波。测量结果表明,当 TE 极化波入射时,拟议的 Van Atta 阵列显示出大于 95° 的 -5 dB 雷达截面 (RCS),而当 TM 极化波入射时,则显示出大于 134° 的 -5 dB 雷达截面 (RCS),大大超过了二维双极化阵列。
