use of antennas in wireless systems is growing because the antenna is the basis of wireless
technologies. In making Antenna Tracker consists of hardware and software. Antenna Tracker
divided into three main sections system, Ground Station, Tracking System and Quadcopter. At the
Quadcopter has GPS and telemetry as the sender of data which is then captured by section Tracking
System via 433 MHz yagi antennas and forwarded to the Mission Planner application on the Ground
Station to display and send data to the Arduino on the Tracking System to be processed using C
programming language results of the process data in PWM which will move the servo to the direction
Quadcopter. For the ability to capture power signal yagi antenna can be up to a distance of 210
meters compared with omni antenna that capture the signal power is only 100 meters away.
