Multifunctional composite structures (MFCS) have become an increasingly important field of research with the large-scale adoption of composite materials in many industrial sectors such as aerospace, automotive, sport and recreation equipment (bikes, scooters, etc.) and maritime. It is a diverse field which includes scientific areas in electromagnetics, electronics, material sciences, structures and structural augmentation, sensors, and thermal management. The paper investigates Conformal Load-bearing Smart Skins (CLSS) as a part of multifunctional composite structures specifically related to aerospace applications and focuses on the seamless incorporation and synergistic coexistence between electronic devices and composite materials. Current trends in materials and manufacturing processes, as well as measurement techniques used to validate both the electromagnetic and structural responses have been explored and discussed. Furthermore, it identifies some of the challenges and complexities associated with CLSS and explores future areas of research which still need to be addressed.

“…Currently, a skin antenna with conformal and load-carrying capability is mainly used. Compared with the traditional airborne antenna, the smart skin antenna technology reduces the weight and volume of the antenna and improves the aerodynamic performance, stealth performance, electronic countermeasure performance, and structure utilization ratio of the aircraft [193][194][195]. With the improvement of process level, the shape of millimeter-wave phased array antenna over 30 GHz will change a lot.…”

Active phased array antenna (APAA) is a representative of complex electronic equipment, and it plays significant roles in scenarios such as battlefield situation perception, aviation guidance, and communication. It has become the core equipment in land, navigation, and aeronautical applications. With the continuous improvement of technical changes and military requirements, the working frequency band, pointing accuracy, gain, and low sidelobe level of APAA increase, and the multi-disciplinary design contradiction between antenna electrical performance and structure and temperature becomes increasingly prominent. As a result, the electrical performance of APAA in service is prone to be affected by the external complex environments. The structural-electromagnetic-thermal (SET) coupling problem has become a key problem restricting the development of APAA. This paper has summarized the structural features and environmental loads of advanced APAA on different platforms and provided design basis and principle for antenna designer. And then the SET coupling theory of APAA has been introduced, which can be applied in both the design and manufacturing stage, as well as the performance control technology in service environment of APAA. This theory helps to analyze the impact of environmental factors, such as antenna structure deformation, radome high-temperature ablation, and feed errors, on the antenna's performance. For 128 × 768 spaceborne array antenna, in the range of 25∼85°C, the gain of antenna decreases with the increase of operating temperature and decreases by 0.015 dB with each increase of 1°C. The key design parameters in the fields of antenna manufacturing accuracy, efficient heat dissipation, and lightweight design are also analysed; for 32 × 32 rectangular planar phased array antenna, the gain of antenna decreases by 2.715 dB when the random error of installation position in x, y, and z direction reaches 1/10 of the wavelength. In addition, condition monitoring, displacement field reconstruction, and electrical performance compensation of APAA have also been touched to help engineers maintain and guarantee the antenna performance throughout its life cycle. Finally, the future research direction of SET technology of APAA has been discussed, and SET technology is extended to more fields such as antenna parameter uncertainty, high-frequency circuit electronics manufacturing, and electronic equipment performance guarantee.

This paper presents a compact wideband circularly-polarized conformal load-bearing microstrip antenna array. The conformal load-bearing antenna structure is an organic honeycomb sandwich structure. When the antenna is embedded in honeycomb sandwich structure, conformal load-bearing antenna is formed. The conformal load-bearing microstrip antenna array has eight layers. Its dimension is 130mm×90mm×11.8mm. Electromagnetic performance of the antenna array is simulated in CST Microwave Studio.The antenna array has simulated -10dB impedance bandwidth of 2.24GHz(19.25-21.49GHz). The 3-dB axial ratio bandwidth of the antenna array is 2.24GHz(19.06-21.3GHz). The gains and patterns of the antenna array are stable in the operating band. The antenna array also has an excellent mechanical performance.
