A system for providing air traffic control within a geographic sector to which a communication frequency in the VHF or UHF range is assigned comprises at least one satellite (configured for a communication with an aircraft in the geographic sector using an analog modulated RFF signal at the communication frequency. The system is configured in such a way that at each time, only one satellite is actively transmitting on the communication frequency assigned to the geographic sector.

An RFIC assembled antenna comprises: a first layer substrate including a first metal pattern, a first slot formed in the first metal pattern, and a second slot formed to be connected to the first slot, and in which an RFIC chip is coupled to a region of the second slot; and a second layer substrate coupled to a lower portion of the first layer substrate and including a second metal pattern, a third slot formed in the second metal pattern, and a dipole radiator formed inside the third slot, wherein a feeding pattern connected to the RFIC chip to provide a feed signal to the dipole radiator is formed inside the first slot.
