Design of wide band underwater antenna using buffer layer structure for underwater communication / Hanisah Mohd Zali

Utilization of electromagnetic wave (EMW) in underwater wireless communication systems is being investigated as the alternative to the conventional acoustic-based system, in order to provide higher data rate. However, underwater EMW systems has the drawback of the high signal attenuation, effecting...
