In this article, a PIN-diode-based high-intensity radiation fields (HIRF) protection method was proposed and the sensitivity to the field intensity of incident wave has been verified by a printed dipole antenna loaded with three pairs of PIN diodes at S-band. To illustrate this method, an equivalent linear circuit was raised to analyze the basic operation principle of the proposed antenna. With a low-power incident wave, the PIN diodes are in off-state and the gain of the proposed antenna remains unaffected; while it drops considerably as the PIN diodes are triggered by HIRF. Furthermore, extensive parametric studies of the structure were analyzed by full-wave simulation to investigate the key factors affecting the performance of HIRF protection and antenna characteristics. Finally, a prototype was fabricated and experiments were implemented to verify the feasibility, which shows a high isolation of 19 dB. To the best of our knowledge, the proposed antenna is the first one to achieve HIRF protection through integrated antenna technology, which features with low cost and compact structure, providing a new perspective.

基于 PIN 二极管的印刷偶极子天线的高强度辐射场 (HIRF) 保护


本文提出了一种基于 PIN 二极管的高强度辐射场（HIRF）保护方法，并通过在 S- 处加载三对 PIN 二极管的印刷偶极子天线验证了对入射波场强的敏感性。乐队。为了说明该方法，提出了等效线性电路来分析所提出的天线的基本工作原理。对于低功率入射波，PIN 二极管处于截止状态，并且所提出的天线的增益不受影响；而当 PIN 二极管被 HIRF 触发时，它会大幅下降。此外，通过全波仿真对结构进行了广泛的参数研究，以研究影响HIRF保护性能和天线特性的关键因素。最后制作了样机并进行了实验验证其可行性，取得了19 dB的高隔离度。据我们所知，该天线是第一个通过集成天线技术实现HIRF防护的天线，具有成本低、结构紧凑的特点，提供了新的视角。
