Abstract

The study projects a flexible and compact wearable pear-shaped Super High Frequency (SHF) antenna that can provide detailed location recognition and tracking applicable to defense beacon technology. This mini aperture with electrical dimensions of 0.12λ₀ × 0.22λ₀ × 0.01λ₀ attains a vast bandwidth over 3.1–34.5 GHz Super High Frequency (SHF) frequency band at S₁₁ ≤ −10 dB, peak gain of 7.14 dBi and proportionately homogeneous radiation pattern. The fractional bandwidth (% BW) acquired is 168% that envelopes diversified frequency spectrum inclusive of X band specifically targeted to all kinds of defense and military operations. The proposed antenna can be worn on a soldier's uniform and hence the Specific Absorption Rate simulation is accomplished. The Peak SAR Value over 1 g of tissue is 1.48 W/kg and for 10 g of tissue is 0.27 W/kg well under the safety standards. The flexibility is proven by analyzing the full electromagnetic simulations for various bending conditions. Time response analysis is attained with its Fidelity Factor and Group Delay. Communication excellence is determined using Link Budget Analysis and it is seen that margin at 100 Mbps is 62 m and at 200 Mbps is 59 m. Prototype is fabricated along with experimental validation. All the results show harmony in shaping the antenna to provide critical situational awareness and data sharing capabilities required in defense beacon technology for location identification.

在国防信标技术中实现高效通信的拉伸可穿戴式 SHF 天线

该研究预测了一种灵活紧凑的可穿戴梨形超高频（SHF）天线，可提供适用于国防信标技术的详细位置识别和跟踪。这种微型孔径的电气尺寸为 0.12λ0 × 0.22λ0 × 0.01λ0，可在 3.1-34.5 GHz 超高频（SHF）频段上获得巨大的带宽，S11 ≤ -10 dB，峰值增益为 7.14 dBi，辐射模式比例均匀。获得的分数带宽（% BW）为 168%，可覆盖包括 X 波段在内的多样化频谱，专门针对各种国防和军事行动。拟议的天线可以佩戴在士兵的制服上，因此可以完成比吸收率模拟。1 克组织的峰值 SAR 值为 1.48 W/kg，10 克组织的峰值 SAR 值为 0.27 W/kg，远低于安全标准。通过分析各种弯曲条件下的全电磁模拟，证明了其灵活性。通过保真系数和群延迟进行时间响应分析。利用链路预算分析确定了通信性能的优劣，100 Mbps 的裕度为 62 米，200 Mbps 的裕度为 59 米。所有结果表明，该天线的形状与国防信标识别技术所需的关键态势感知和数据共享功能相吻合。
