Underwater Antenna Technologies with Emphasis on Submarine and Autonomous Underwater Vehicles (AUVs)

Electronics
Following the persistent evolution of terrestrial 5G wireless systems, a new field of underwater communication has emerged for various related applications like environmental monitoring, underwater mining, and marine research. However, establishing reliable high-speed underwater networks remains notoriously difficult due to the severe RF attenuation in
