DESIGN OF 433MHZ YAGI ANTENNA ON AUTOMATIC ANTENNA TRACKER FOR UNMANNED AERIAL VEHICLE
Small Scale Mapping Sector uses UAV (Unmanned Aerial Vehicle) as a mapping tool. UAVs require wireless and long-distance communication. For this reason, an antenna with a far beam pattern and a high gain are needed. This research uses the Yagi Antenna because it has a directional beam pattern but has a weakness that is, the yagi antenna must be directed by pointing to connect the communication between the antenna and the UAV. Based on the results of the calculation and simulation of the yagi antenna with a frequency of 433 MHz, a gain of 14.2 dBi was obtained. Yagi antenna designs are made using aluminum and copper. From the results of the communication distance test, obtained a range of ± 5 km. The test is carried out by attaching the yagi antenna to the receiver of the 433 MHz telemetry module, then the transceiver module is installed in the UAV.
