Rancang Bangun Antena Yagi 433 MHZ Pada Automatic Antenna Tracker Untuk Pesawat Terbang Tanpa Awak

Abstract: Bidang pemetaan lahan skala kecil menggunakan UAV (Unmanned Aerial Vehicle) sebagai sarana  pemetaan. UAV memerlukan komunikasi tanpa kabel (wireless) dengan jarak yang jauh dan stabil. Untuk itu dibutuhkan sebuah antena dengan pola pancaran yang jauh dan penguatan (gain) yang tinggi. Penelitian ini menggunakan Antena Yagi karena memiliki pola pancaran yang terarah (directional)  tetapi memilki kelemahan yaitu, antena yagi harus diarahkan secara pointing untuk menjaga komunikasi antara antena dan UAV. Berdasar… Show more

“…The 5-element Yagi antenna is a type of directional antenna, which is an antenna that can only be directed in certain directions to transmit and receive electromagnetic waves [14]. The Yagi antenna consists of a dipole element as the main radiation transmitter, a reflector element as a radiation-reflecting element, and director elements that function to narrow the beam angle in a straight and directional manner so that the radiation pattern can be narrowed, and the distance travelled is farther than other types of antennas at the same power input [15]. The 5-element Yagi antenna used has a working frequency of 433 MHz, which is the same as that of the Ebyte E22-400T30D LoRa module used, which is 433 MHz.…”
