Antenna. z Antennas form a very important element in communication system, either terrestrial or extra terrestrial, depending on the mission type and requirements. z "That part of a transmitting or receiving system which is designed to radiate or to receive electromagnetic waves". Slot antenna - Wikipedia A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna.
