5 Working principle of ATG airborne antenna

The ATG airborne antenna is the transmitting and receiving component of the wireless signal of the airborne ATG system. It is installed outside the aircraft body and is responsible for the communication between the aircraft and the ground.

ATG wireless signal reception and transmission.

The ATG airborne antenna uses the internal antenna oscillator to receive the electromagnetic wave signal emitted by the ground ATG base station into the air and convert it into a radio frequency signal.

It is transmitted to the ATG airborne terminal for processing through the radio frequency cable.

The ATG airborne antenna uses the internal antenna oscillator to receive the radio frequency signal of the ATG airborne terminal through the radio frequency cable and convert it into electromagnetic wave the number is radiated from the air and received by the ground ATG base station.

6 Basic requirements

7 Functions

8 Ports

At least one radio frequency interface should be provided, and the interface type should match the radio frequency interface of the ATG airborne terminal.

9 Environmental test

The environmental test of the antenna shall meet the relevant requirements of RTCA/DO-160G.
