Wireless electronic systems have been relying on dish antennas to send and receive signals. These systems have been widely used where directivity is important and many of those systems work well at a relatively low cost after years of optimization. These dish antennas having a mechanical arm to rotate the …

UUVs—submersible unmanned vehicles—are divided into two categories: remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUVs). ROVs are controlled and powered by a person or crew on either land or neighboring craft via an umbilical or using remote control. The cables enable maneuverability of the ROV, allowing it to travel …
