The rapid expansion of commercial applications will continue to add wireless congestion in the available electromagnetic spectrum (EMS). Consequently, operating frequencies are becoming increasingly spread across a wider portion of the spectrum. Inevitably, there is suboptimal resource utilization, when multiple narrowband antennas operate independently. To address this challenge, ultra-wideband (UWB) arrays offer a compelling alternative by consolidating multiple frequency bands into a single aperture. This approach can greatly reduce the total size, weight, power and cost (SWAP-C) of the system. Notably, traditional tapered volumetric arrays have high profiles and lack conformality. Alternatively, the tightly-coupled dipoles arrays (TCDAs) have emerged as the leading solution, due to their extremely low-profiles, high efficiency, cross-polarization purity and low-angle scanning capabilities. This paper provides a comprehensive review on TCDAs, offering an in-depth analysis of their operating principles and state-of-the-art implementations, from the early 2000s to the present day.
