Abstract

This letter introduces a hybrid electromagnetic transparency regulation method that synergistically integrates low-loss transmission and high-impedance choke characteristics, applied to the design of a wideband multiband shared aperture array. A dual-nested square ring is employed as the fundamental transmission unit, which not only establishes the first passband over 1.7 GHz to 2.1 GHz (middle-band, MB) but also utilizes its outer ring as the radiator for the low-band (LB) antenna operating from 0.68 GHz to 0.86 GHz. Dual wideband parallel LC (PLC) resonators are subsequently incorporated into both the inner and outer square rings. At their resonance frequencies, the high-impedance characteristics effectively suppress the induced currents on the nested square rings, producing open-circuit effects that fragment the structure into discrete electrically small elements and thereby render it electromagnetically transparent, covering the two high-bands (HB, HB1: 3 GHz to 4 GHz and HB2: 4.6 GHz to 5.5 GHz). Consequently, a quad-band wideband shared-aperture array is successfully realized, demonstrating the effectiveness of the proposed hybrid design strategy.

基于混合电磁透明调节的多频带宽带共享孔径阵列

本文介绍了一种混合电磁透明调节方法，该方法协同集成了低损耗传输和高阻抗扼流圈特性，并应用于宽带多频带共享孔径阵列的设计。采用双嵌套方形环作为基本传输单元，不仅建立了1.7 GHz至2.1 GHz（中频，MB）的第一通带，而且利用其外环作为0.68 GHz至0.86 GHz的低频段（LB）天线的辐射器。双宽带并行LC （PLC）谐振器随后被并入内外方环。在它们的共振频率下，高阻抗特性有效地抑制了嵌套方形环上的感应电流，产生开路效应，将结构分割成离散的电小元件，从而使其电磁透明，覆盖两个高频段（HB， HB1: 3 GHz至4 GHz和HB2: 4.6 GHz至5.5 GHz）。最后，成功实现了四波段宽带共享孔径阵列，验证了混合设计策略的有效性。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
