As an important part of very high frequency(VHF) communication system on civil aircraft, VHF communication antennas transform energy while transmitting and receiving electromagnetic wave. The design of VHF communication antennas affects the radio frequency (RF) energy distribution of communication directly, and then affects the flight safety. This paper introduces the VHF communication system briefly. Based on the given design principles of VHF communication antenna, the process of designing VHF communication antenna is analyzed by an engineering example. Finally, the characteristics of designing VHF communication antennas are summarized.
