High preference helical airborne antenna design for UAV

The mobile communication system, whose most remarkable advantages are convenience, stability, and extensibility, has been widely applied in daily life. Depending on the structure of the mobile communication system, the signals can be stretched through the UAV with the repeater platform, which can help to prove the connection rapidly with communication dead zones. A high performance helical antenna used for data transmission on UAV will be design and constructed in present work. There are three main experimental steps. The feasibility evaluation, connection distance and the calculation of receive sensitivity are the first step. Second, follow the limitations and conditions of UAV to launch the experiments. Finally, to use 2-stage tests which were shielded RF Anechoic Chamber and aviation experimental region, and provide the best control parameter to future modification from experimental data.
