That portion, usually wires or rods, of a radio transmitter or receiver station used for radiating waves into or receiving them from space. It changes electrical currents into electromagnetic waves, and vice versa.. The preceding MAC protocols have been designed for omni-directional transmissions, and may not fully exploit the potentialsof directional antennas. The physical CS may suffer fromdirectional transmis By: Dillon . L. indsey. What is a wormhole?. A wormhole is a tunnel in space that Connects space time. . A wormhole is usually formed when two masses put the right amount of force on space time to create time travel. . Dr. Kupervasser Oleg. Second law of thermodynamics.
