Underwater wireless communications links have almost exclusively been implemented using acoustic systems. Optical links have provedimpractical for many applications. Although underwater radio links were experimented in the pioneering days of radio, they did not meet the requirements of the time. Given modern operational requirements and digital communications technology, the time is now ripe for using electromagnetic signals in the underwater environment. Electromagnetic propagation is more than a hundred times faster than acoustic, which can have important advantages for command latency and networking protocols, where many signals have to be exchanged. The main objective of the proposed activity is to design, manufacture and test a low cost / low profile antenna and transponder unit that performs well in a marine environment based on use of electromagnetic signals
