“…Then, once the laminate had been cured, silver ink was additively printed onto the back surface to create the remaining parts of the control circuitry. Follow-up work by the authors also described a more complex demonstration of an integrated FMCW radar front-end transceiver using a similar approach [179].…”

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.

“…Over the years, several developments have been proposed in this regard such as surface antenna structures, composite smart structures and 3D integrated microstrip antenna structures to further enhance structural and electrical efficiency [ 4 , 5 , 6 , 7 , 8 ]. Recently, a frequency-modulated continuous wave (FMCW) radar front-end was embedded inside an aerospace composite [ 9 ]. The manufacturing process for highly integrated embedded antennas is very complex and can lead to irregularities.…”

The integration of antennas in composite structures is gaining popularity with advances in wireless communications and the ever-increasing demands for efficient smart structures. Efforts are ongoing to ensure that antenna-embedded composite structures are robust and resilient to inevitable impacts, loading and other external factors that threaten the structural integrity of these structures. Undoubtedly, the in situ inspection of such structures to identify anomalies and predict failures is required. In this paper, the microwave non-destructive testing (NDT) of antenna-embedded composite structures is introduced for the first time. The objective is accomplished using a planar resonator probe operating in the UHF frequency range (~525 MHz). High-resolution images of a C-band patch antenna fabricated on an aramid paper-based honeycomb substrate and covered with a glass fiber reinforced polymer (GFRP) sheet are presented. The imaging prowess of microwave NDT and its distinct advantages in inspecting such structures are highlighted. The qualitative as well as the quantitative evaluation of the images produced by the planar resonator probe and a conventional K-band rectangular aperture probe are included. Overall, the potential utility of microwave NDT for the inspection of smart structures is demonstrated.

“…Conformal load-bearing antenna structures (CLAS) offer the opportunity to integrate communication and sensing capabilities into load-bearing airframes [ 1 , 2 , 3 ], as illustrated in Figure 1 . Microstrip patch antennas are one simple example that can easily be integrated into typical conformal airframe structures.…”

One of the important functions of antennas is to facilitate wireless communication. The IEEE 802.11 is part of the IEEE802 set of local area network technical standards, and specifies the media access control and physical layer protocols for implementing wireless local area network computer communication. The network physical layer protocol with a centre frequency of 2.4 GHz has a bandwidth of 22 MHz. A conformal load-bearing antenna structure (CLAS) facilitating this communication band that is tuned to 2.4 GHz must remain within this bandwidth. The aim of this paper is to investigate the effects of mechanical loading imposed on a load-bearing patch antenna with respect to its ability to remain within the specified bandwidth. The mechanical loading configurations considered include tensile, biaxial, and twisting. This paper will also report on the response of the antenna patch to the presence of a disbond between the metallised antenna and its substrate, which can arise due to fabrication anomalies and operational usage. This numerical work will assist in the design of experimental testing of the mechanical and electromagnetic properties of an embedded CLAS, which will ultimately be used to inform selection of appropriate regions to place patch antennas on load-bearing deformable surfaces.
