With the continuous development of communication technology, the communication methods of civil aircraft are also increasingly updated. At present, there are three main methods for civil aircraft, namely high frequency communication system,very high frequency system and satellite communication system. The antenna is the last stage of communication equipment，and its structure and performance will directly affect the communication quality of the entire radio system. This article briefly introduces the basic radiation principles and engineering examples of high-frequency and satellite communication antennas. The high-frequency communication antenna adopts the form of a loop antenna, while the satellite communication antenna adopts the phased array antenna form of 2×6, and the phased array antenna unit adopts the microstrip patch antenna form of gap coupling feeding. Finally the development of communication antenna is prospected.
