The rapid development of unmanned systems and wearable technology has propelled mobile-platform conformal array antennas to the forefront of wireless communication research. These arrays are distinguished by their minimal disturbance to the aerodynamic profile of the host platform, exceptional space utilization efficiency, and proactive robustness in complex electromagnetic environments. Traditional planar array antennas face significant bottlenecks on mobile platforms, including limited scanning ranges, inadequate polarization flexibility, and poor integration with the platform structure. Conformal array antennas overcome these constraints by conforming to the host surface, significantly improving beam coverage, enhancing attitude compatibility, and ultimately delivering superior communication performance for mobile scenarios. This chapter focuses on conformal array antennas for mobile platforms. Addressing critical emergency response scenarios—such as firefighting and military operations—we confront the core challenges of dynamic environmental adaptability and multifunctional integration. To this end, we present innovative solutions: a cylindrical conformal array antenna integrated onto unmanned aerial vehicles (UAVs) and a spherical conformal array antenna integrated into helmets for typical emergency rescue scenario as shown in Fig. 3.1.
