Abstract

This paper presents a modularized reconfigurable functional electromagnetic surface (MRFES) for broadband absorption and polarization conversion by using tightly coupled dipole antennas (TCDA) and back-loaded radio frequency (RF) circuits (BLRFC). A dual-polarized antenna array with tight coupling and wide angular scanning characteristics is designed. By loading different RF circuits on the back side of the antenna array's ground plane, switchable broadband absorption and polarization conversion functions are achieved. The design adopts modularization to facilitate the replacement of back-loaded RF circuits for diverse electromagnetic (EM) control functions. The final design of the tightly coupled antenna array has a thickness of 13.437 mm and a size of 119.5 mm × 119.5 mm. It works in a bandwidth range of 4.14-13 GHz. Upon loading the absorption circuit board, a broadband absorbing electromagnetic (EM) surface is formed, achieving dual-polarization absorption within a bandwidth of 4.14-12.4 GHz. With the polarization conversion circuit board attached, polarization conversion effects are realized within a bandwidth of 4.4-12.9 GHz. Both simulations and experiments verify that the designed EM surface possesses modular reconfigurable functions for broadband absorption/polarization conversion. The proposed design scheme holds promising prospects for applications in active stealth, adaptive camouflage, intelligent communication and other fields.

摘要

本文提出了一种模块化可重构功能电磁表面（MRFES），通过使用紧密耦合偶极天线（TCDA）和背加载射频（RF）电路（BLRFC）实现宽带吸收和极化转换。设计了一种具有紧密耦合和宽角度扫描特性的双极化天线阵列。通过在天线阵列接地平面的背面加载不同的射频电路，实现了可切换的宽带吸收和极化转换功能。该设计采用模块化，便于更换背加载射频电路以实现多种电磁（EM）控制功能。紧密耦合天线阵列的最终设计厚度为13.437毫米，尺寸为119.5毫米×119.5毫米。它在4.14 - 13吉赫兹的带宽范围内工作。加载吸收电路板后，形成宽带吸收电磁（EM）表面，在4.14 - 12.4吉赫兹的带宽内实现双极化吸收。附上极化转换电路板后，在4.4 - 12.9吉赫兹的带宽内实现极化转换效果。仿真和实验均验证了所设计的电磁表面具有用于宽带吸收/极化转换的模块化可重构功能。所提出的设计方案在有源隐身、自适应伪装、智能通信等领域具有广阔的应用前景。
