摘要
为改善无线多波段的辐射特性，提出了一种纳米复合材料填充柔性紧凑圆形多波段天线。将八木形辐射体改进为共面波导馈电环形贴片和覆盖6个波段的地，通过在馈电线上填充与环形辐射体位置对应的纳米复合材料槽，增强了八木形辐射体的隔离性和辐射强度。聚苯胺（PANI）是一种导电聚合物，具有许多优点。它的电导率通过调节质子水平在氧化还原反应中有很大的变化。碳包覆钴（CCo）和二氯乙酸（DCAA）的结合产生了一种均匀的溶液，该溶液具有CCo的铁磁性。这种磁介质纳米复合天线是通过将包裹在CCo溶液中的混合物均质化而形成的。利用聚苯胺的电学性能调制CCo的磁性能，提高了天线的电磁辐射，提出了适用于不同弯曲条件的纳米复合材料CCo_PANI。通过不同弯曲条件对天线的灵活性进行了评估，结果与刚性天线相匹配，覆盖了1.80-2.45 GHz PCS、2.5/3.5 GHz WiMAX、5G NR 78、5G sub 6 GHz、Lower 6 GHz 5G、5.80 GHz WLAN和5.80 GHz ISM频段。
A nanocomposite filled compact circular Hexa band radiator from a traditional Yagi antenna structure with enhanced radiation for flexible wireless applications
A Nanocomposite filled flexible compact circular shaped multiband antenna proposed for improving radiation characteristics of various wireless bands. A Yagi shaped radiator modified to a coplanar waveguide fed circular ring patch and ground that cover six bands with good isolation and its radiation is enhanced by nanocomposite filled slots in feed line that corresponds to the position of circular ring radiator. Polyaniline (PANI) a conducting polymers exhibits numerous benefits. Its conductivity greatly varies through redox reactions by adjusting proton levels. The combination of carbon coated cobalt (CCo) and dichloroacetic acid (DCAA) creates a homogeneous solution with magnetic properties from the ferromagnetic nature of CCo. This magnetodielectric nanocomposite antenna is formed by homogenizing a mixture encased with CCo solution. The electromagnetic radiation of antenna is increased by modulation of magnetic properties of CCo with electric properties of PANI and this proposed nanocomposite material CCo_PANI suitable for different bending conditions. The flexibility of antenna evaluated by different bending conditions, results are matched to rigid antenna and covers 1.80–2.45 GHz PCS, 2.5/3.5 GHz WiMAX, 5G NR 78, 5G sub 6 GHz, Lower 6 GHz 5G, 5.80 GHz WLAN and 5.80 GHz ISM bands.
