Abstract

In high-speed microelectronic communication, efficient and reliable radome-enclosed antenna performance is highly desired, which depends on consistent dielectric, mechanical properties, and low moisture absorption. The purpose of this study is to investigate the dielectric properties of fiber-polymer matrix composite (PMC) radome over wideband frequency and the impact of environmental aging on its performance. The dielectric constant (Ɛr) of the SF/E0.8 (80% fiber loading) composite radome material decreased to 4% from its original value (3.93), and dielectric loss (δ) was reduced by 11% from 0.035 (2–18 GHz), while SEM morphology indicated fair interface bonding. Employing the Hallberg and Peck model, equivalent aging time (5–25 years), upon accelerated environmental aging, Ɛr was increased up to 3.69%, δ to 9.68%, and the moisture uptake in the SF/E0.8 composite was increased from 1.13% to 1.67%, while tensile strength was retained up to 90.62% of its original value (147.83 MPa), compression strength up to 93.56% of its original value (388.54 MPa), flexural strength up to 85.44% of its original value (286.77 MPa), and interlaminar shear strength up to 77.66% of its original value (22.03 MPa), respectively. SF/E0.8 radome-enclosed antenna gain was decreased to 1%, and the voltage standing wave ratio (VSWR) was increased to 1.04% from their original values. This gradual and small deviation of SF/Ex composite properties and radome electrical performance over the extended aging time is referred to as reliable and effective for radome applications.

增强聚合物复合材料雷达罩的环境老化：可靠性和性能调查

在高速微电子通信中，高效可靠的天线罩封闭天线性能非常重要，这取决于稳定的介电性能、机械性能和低吸湿性。本研究的目的是研究纤维-聚合物基复合材料（PMC）天线罩在宽带频率下的介电性能以及环境老化对其性能的影响。SF/E0.8 (80% 纤维负载) 复合天线罩材料的介电常数 (Ɛr)从原始值 (3.93) 降低到 4%，介电损耗 (δ) 从 0.035 (2-18 GHz) 降低了 11%，而 SEM 形貌表明界面结合良好。采用 Hallberg 和 Peck 模型，等效老化时间（5-25 年）、加速环境老化后，Ɛr 增加到 3.69%，δ 增加到 9.68%，SF/E0.8 复合材料的吸湿率从 1.13% 增加到 1.67%，而拉伸强度保持在原始值的 90.62% （147.83 兆帕），压缩强度达到原始值的 93.56% （388.54 兆帕），弯曲强度达到原始值的 85.44% （286.77 兆帕），层间剪切强度达到原始值的 77.66% （22.03 兆帕）。SF/E0.8 雷达天线增益下降到 1%，电压驻波比 (VSWR) 从原始值增加到 1.04%。这种 SF/Ex 复合材料性能和雷达罩电气性能在延长的老化时间内逐渐出现的微小偏差被认为是雷达罩应用中可靠和有效的。
